Class DocumentNode

java.lang.Object
  extended by biz.c24.io.api.data.saxon.DocumentNode
All Implemented Interfaces:
DataNode, Node, Source, net.sf.saxon.evpull.PullEvent, net.sf.saxon.om.DocumentInfo, net.sf.saxon.om.Item, net.sf.saxon.om.NodeInfo, net.sf.saxon.om.ValueRepresentation

public class DocumentNode
extends Object
implements net.sf.saxon.om.DocumentInfo, Node, DataNode

A document node in the C24 Integreation Objects data model. This does not correspond to any actual object in the model, but is linked to the ComplexDataObject representing the outermost element.

This class implements the Saxon DocumentInfo interface representing a document node; it therefore also implements NodeInfo interface representing a Node in the XDM data model. It also implements the JAXP Source interface, allowing it to be used directly as the source of an XSLT transformation.

Method Detail

getUnderlyingObject

public Object getUnderlyingObject()
Description copied from interface: DataNode
Returns the underlying object, such as the String, Integer, Date, or ComplexDataObject.

Specified by:
getUnderlyingObject in interface DataNode
Returns:
The underlying object.

isIgnoreDocumentNode

public boolean isIgnoreDocumentNode()
Returns whether this node will be ignored whilst traversing the descendant axis.

Returns:
Whether to skip the document node whilst traversing the descendant axis.

isNamespaceAware

public boolean isNamespaceAware()
Returns whether this is a namespace aware node.

Returns:
Whether this is a namespace aware node.

getRelativePosition

public int getRelativePosition()
Get the position of this node relative to its siblings

Specified by:
getRelativePosition in interface Node
Returns:
zero, since a document node has no siblings

getUnparsedEntity

public String[] getUnparsedEntity(String name)
Get the unparsed entity with a given name

Specified by:
getUnparsedEntity in interface net.sf.saxon.om.DocumentInfo
Parameters:
name - the name of the entity
Returns:
Unparsed entities are not supported in this implementation. The method always returns null.

selectID

public net.sf.saxon.om.NodeInfo selectID(String id)
Get the element with a given ID, if any

Specified by:
selectID in interface net.sf.saxon.om.DocumentInfo
Parameters:
id - the required ID value
Returns:
the element with the required ID value; or null if there is no such element.

atomize

public net.sf.saxon.value.Value atomize()
                                 throws net.sf.saxon.trans.XPathException
Get the typed value. The result of this method will always be consistent with the method Item.getTypedValue(). However, this method is often more convenient and may be more efficient, especially in the common case where the value is expected to be a singleton.

Specified by:
atomize in interface net.sf.saxon.om.NodeInfo
Returns:
the typed value. This will either be a single AtomicValue or a Value whose items are atomic values.
Throws:
net.sf.saxon.trans.XPathException
Since:
8.5

compareOrder

public int compareOrder(net.sf.saxon.om.NodeInfo other)
Determine the relative position of this node and another node, in document order.

The other node must always be in the same tree; the effect of calling this method when the two nodes are in different trees is undefined. To obtain a global ordering of nodes, the application should first compare the result of getDocumentNumber(), and only if the document number is the same should compareOrder() be called.

Specified by:
compareOrder in interface net.sf.saxon.om.NodeInfo
Parameters:
other - The other node, whose position is to be compared with this node
Returns:
-1 if this node precedes the other node, +1 if it follows the other node, or 0 if they are the same node. (In this case, isSameNode() will always return true, and the two nodes will produce the same result for generateId())
Since:
8.4

signum

public static int signum(int c)
Convenience method: return the signum of an integer

Parameters:
c - a signed integer
Returns:
-1, 0, or +1 according to whether c is negative, zero, or positive

copy

public void copy(net.sf.saxon.event.Receiver out,
                 int whichNamespaces,
                 boolean copyAnnotations,
                 int locationId)
          throws net.sf.saxon.trans.XPathException
Copy this node to a given outputter.

This method is primarily for internal use. It should not be considered a stable part of the Saxon API.

Specified by:
copy in interface net.sf.saxon.om.NodeInfo
Parameters:
out - the Receiver to which the node should be copied
whichNamespaces - in the case of an element, controls which namespace nodes should be copied. Values are NodeInfo.NO_NAMESPACES, NodeInfo.LOCAL_NAMESPACES, NodeInfo.ALL_NAMESPACES
copyAnnotations - indicates whether the type annotations of element and attribute nodes should be copied
locationId - If non-zero, identifies the location of the instruction that requested this copy. If zero, indicates that the location information for the original node is to be copied; in this case the Receiver must be a LocationCopier
Throws:
net.sf.saxon.trans.XPathException

generateId

public void generateId(net.sf.saxon.om.FastStringBuffer buffer)
Construct a character string that uniquely identifies this node. Note: a.isSameNode(b) if and only if generateId(a)==generateId(b)

Specified by:
generateId in interface net.sf.saxon.om.NodeInfo
Parameters:
buffer - a buffer which will be updated to hold a string that uniquely identifies this node, across all documents.
Since:
8.7

Changed in Saxon 8.7 to generate the ID value in a client-supplied buffer


getAttributeValue

public String getAttributeValue(int fingerprint)
Get the string value of a given attribute of this node

Specified by:
getAttributeValue in interface net.sf.saxon.om.NodeInfo
Parameters:
fingerprint - The fingerprint of the attribute name
Returns:
the attribute value if it exists, or null if it does not exist. Always returns null if this node is not an element.
Since:
8.4

getBaseURI

public String getBaseURI()
Get the Base URI for the node, that is, the URI used for resolving a relative URI contained in the node. This will be the same as the System ID unless xml:base has been used. Where the node does not have a base URI of its own, the base URI of its parent node is returned.

Specified by:
getBaseURI in interface net.sf.saxon.om.NodeInfo
Returns:
the base URI of the node. This may be null if the base URI is unknown.
Since:
8.4

getConfiguration

public net.sf.saxon.Configuration getConfiguration()
Get the configuration used to build the tree containing this node.

Specified by:
getConfiguration in interface net.sf.saxon.om.NodeInfo
Returns:
the Configuration
Since:
8.4

getDeclaredNamespaces

public int[] getDeclaredNamespaces(int[] buffer)
Get all namespace undeclarations and undeclarations defined on this element.

This method is intended primarily for internal use. User applications needing information about the namespace context of a node should use iterateAxis(Axis.NAMESPACE).

Specified by:
getDeclaredNamespaces in interface net.sf.saxon.om.NodeInfo
Parameters:
buffer - If this is non-null, and the result array fits in this buffer, then the result may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.
Returns:
An array of integers representing the namespace declarations and undeclarations present on this element. For a node other than an element, return null. Otherwise, the returned array is a sequence of namespace codes, whose meaning may be interpreted by reference to the name pool. The top half word of each namespace code represents the prefix, the bottom half represents the URI. If the bottom half is zero, then this is a namespace undeclaration rather than a declaration. The XML namespace is never included in the list. If the supplied array is larger than required, then the first unused entry will be set to -1.

For a node other than an element, the method returns null.


getDisplayName

public String getDisplayName()
Get the display name of this node, in the form of a lexical QName. For elements and attributes this is [prefix:]localname. For unnamed nodes, it is an empty string.

Specified by:
getDisplayName in interface net.sf.saxon.om.NodeInfo
Returns:
The display name of this node. For a node with no name, returns an empty string.
Since:
8.4

getDocumentNumber

public int getDocumentNumber()
Get the document number of the document containing this node. For a free-standing orphan node, just return the hashcode.

Specified by:
getDocumentNumber in interface net.sf.saxon.om.NodeInfo
Since:
8.4

getDocumentRoot

public net.sf.saxon.om.DocumentInfo getDocumentRoot()
Get the root node, if it is a document node.

Specified by:
getDocumentRoot in interface net.sf.saxon.om.NodeInfo
Returns:
the DocumentInfo representing the containing document. If this node is part of a tree that does not have a document node as its root, returns null.
Since:
8.4

getFingerprint

public int getFingerprint()
Get fingerprint. The fingerprint is a coded form of the expanded name of the node: two nodes with the same name code have the same namespace URI and the same local name. The fingerprint contains no information about the namespace prefix. For a name in the null namespace, the fingerprint is the same as the name code.

Specified by:
getFingerprint in interface net.sf.saxon.om.NodeInfo
Returns:
an integer fingerprint; two nodes with the same fingerprint have the same expanded QName. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.
Since:
8.4

getLineNumber

public int getLineNumber()
Get line number. Line numbers are not maintained by default, except for stylesheets and schema documents. Line numbering can be requested using the -l option on the command line, or by setting options on the TransformerFactory or the Configuration before the source document is built.

The granularity of line numbering is normally the element level: for other nodes such as text nodes and attributes, the line number of the parent element will normally be returned.

In the case of a tree constructed by taking input from a SAX parser, the line number will reflect the SAX rules: that is, the line number of an element is the line number where the start tag ends. This may be a little confusing where elements have many attributes spread over multiple lines, or where single attributes (as can easily happen with XSLT 2.0 stylesheets) occupy several lines.

In the case of a tree constructed by a stylesheet or query, the line number may reflect the line in the stylesheet or query that caused the node to be constructed.

The line number can be read from within an XPath expression using the Saxon extension function saxon:line-number()

Specified by:
getLineNumber in interface net.sf.saxon.om.NodeInfo
Returns:
the line number of the node in its original source document; or -1 if not available
Since:
8.4

getLocalPart

public String getLocalPart()
Get the local part of the name of this node. This is the name after the ":" if any.

Specified by:
getLocalPart in interface net.sf.saxon.om.NodeInfo
Returns:
the local part of the name. For an unnamed node, returns "". Unlike the DOM interface, this returns the full name in the case of a non-namespaced name.
Since:
8.4

getNameCode

public int getNameCode()
Get name code. The name code is a coded form of the node name: two nodes with the same name code have the same namespace URI, the same local name, and the same prefix. By masking the name code with NamePool.FP_MASK, you get a fingerprint: two nodes with the same fingerprint have the same local name and namespace URI.

Specified by:
getNameCode in interface net.sf.saxon.om.NodeInfo
Returns:
an integer name code, which may be used to obtain the actual node name from the name pool. For unnamed nodes (text nodes, comments, document nodes, and namespace nodes for the default namespace), returns -1.
Since:
8.4
See Also:
allocate, getFingerprint

getNamePool

public net.sf.saxon.om.NamePool getNamePool()
Get the NamePool that holds the namecode for this node

Specified by:
getNamePool in interface net.sf.saxon.om.NodeInfo
Returns:
the namepool
Since:
8.4

getNodeKind

public int getNodeKind()
Get the kind of node. This will be a value such as Type.ELEMENT or Type.ATTRIBUTE. There are seven kinds of node: documents, elements, attributes, text, comments, processing-instructions, and namespaces.

Specified by:
getNodeKind in interface net.sf.saxon.om.NodeInfo
Returns:
an integer identifying the kind of node. These integer values are the same as those used in the DOM
Since:
8.4
See Also:
Type

getParent

public net.sf.saxon.om.NodeInfo getParent()
Get the NodeInfo object representing the parent of this node

Specified by:
getParent in interface net.sf.saxon.om.NodeInfo
Returns:
the parent of this node; null if this node has no parent
Since:
8.4

getPrefix

public String getPrefix()
Get the prefix of the name of the node. This is defined only for elements and attributes. If the node has no prefix, or for other kinds of node, returns a zero-length string.

Specified by:
getPrefix in interface net.sf.saxon.om.NodeInfo
Returns:
The prefix of the name of the node.
Since:
8.4

getRoot

public net.sf.saxon.om.NodeInfo getRoot()
Get the root node of the tree containing this node

Specified by:
getRoot in interface net.sf.saxon.om.NodeInfo
Returns:
the NodeInfo representing the top-level ancestor of this node. This will not necessarily be a document node. If this node has no parent, then the method returns this node.
Since:
8.4

getStringValue

public String getStringValue()
Return the string value of the node. This is normally the string value as defined in the XPath data model, except that no distinction is made between strings and untyped atomic values.

The interpretation of this depends on the type of node. For an element it is the accumulated character content of the element, including descendant elements.

This method returns the string value as if the node were untyped. Unlike the string value accessor in the XPath 2.0 data model, it does not report an error if the element has a complex type, instead it returns the concatenation of the descendant text nodes as it would if the element were untyped.

Specified by:
getStringValue in interface net.sf.saxon.om.Item
Specified by:
getStringValue in interface net.sf.saxon.om.NodeInfo
Specified by:
getStringValue in interface net.sf.saxon.om.ValueRepresentation
Returns:
the string value of the node
Since:
8.4

getSystemId

public String getSystemId()
Get the System ID for the node. Note this is not necessarily the same as the base URI: the base URI can be modified by xml:base, but the system ID cannot. The base URI is used primarily for resolving relative URIs within the content of the document. The system ID is used primarily in conjunction with a line number, for identifying the location of elements within the source XML, in particular when errors are found.

Specified by:
getSystemId in interface Source
Specified by:
getSystemId in interface net.sf.saxon.om.NodeInfo
Returns:
the System Identifier of the entity in the source document containing the node, or null if not known. For this implementation, the base URI is returned.
Since:
8.4

getTypeAnnotation

public int getTypeAnnotation()
Get the type annotation of this node, if any. The type annotation is represented as an integer; this is the fingerprint of the name of the type, as defined in the name pool. Anonymous types are given a system-defined name. The value of the type annotation can be used to retrieve the actual schema type definition using the method Configuration.getSchemaType(int).

The bit IS_DTD_TYPE (1<<30) will be set in the case of an attribute node if the type annotation is one of ID, IDREF, or IDREFS and this is derived from DTD rather than schema validation.

Specified by:
getTypeAnnotation in interface net.sf.saxon.om.NodeInfo
Returns:
the type annotation of the node, under the mask NamePool.FP_MASK, and optionally the bit setting IS_DTD_TYPE in the case of a DTD-derived ID or IDREF/S type (which is treated as untypedAtomic for the purposes of obtaining the typed value).

The result is undefined for nodes other than elements and attributes.

Since:
8.4

getURI

public String getURI()
Get the URI part of the name of this node. This is the URI corresponding to the prefix, or the URI of the default namespace if appropriate.

Specified by:
getURI in interface net.sf.saxon.om.NodeInfo
Returns:
The URI of the namespace of this node. For an unnamed node, or for an element or attribute that is not in a namespace, or for a processing instruction, returns an empty string.
Since:
8.4

hasChildNodes

public boolean hasChildNodes()
Determine whether the node has any children.

Note: the result is equivalent to
iterateAxis(Axis.CHILD).next() != null

Specified by:
hasChildNodes in interface net.sf.saxon.om.NodeInfo
Returns:
True if the node has one or more children
Since:
8.4

isSameNodeInfo

public boolean isSameNodeInfo(net.sf.saxon.om.NodeInfo other)
Determine whether this is the same node as another node.

Note that two different NodeInfo instances can represent the same conceptual node. Therefore the "==" operator should not be used to test node identity. The equals() method is not overridden for nodes, so it has the same effect as using "==".

Note: a.isSameNodeInfo(b) if and only if generateId(a)==generateId(b).

This method has the same semantics as isSameNode() in DOM Level 3, but works on Saxon NodeInfo objects rather than DOM Node objects.

Specified by:
isSameNodeInfo in interface net.sf.saxon.om.NodeInfo
Parameters:
other - the node to be compared with this node
Returns:
true if this NodeInfo object and the supplied NodeInfo object represent the same node in the tree. For this implementation, this is based on object identity: if the same element is wrapped in two different document nodes, they are considered to represent different documents.

equals

public boolean equals(Object obj)
Indicates whether some other object is "equal to" this one.

equals() returns the same result as isSameNodeInfo(): true if the two objects represent the same node

Specified by:
equals in interface net.sf.saxon.om.NodeInfo
Overrides:
equals in class Object
Parameters:
obj - the reference object with which to compare.
Returns:
true if this object is the same as the obj argument; false otherwise.
See Also:
hashCode()

hashCode

public int hashCode()
Returns a hash code value for the object.

Specified by:
hashCode in interface net.sf.saxon.om.NodeInfo
Overrides:
hashCode in class Object
Returns:
a hash code value for this object.
See Also:
Object.equals(Object)

iterateAxis

public net.sf.saxon.om.AxisIterator iterateAxis(byte axisNumber)
Return an iteration over all the nodes reached by the given axis from this node

Specified by:
iterateAxis in interface net.sf.saxon.om.NodeInfo
Parameters:
axisNumber - an integer identifying the axis; one of the constants defined in class Axis
Returns:
an AxisIterator that scans the nodes reached by the axis in turn.
Throws:
UnsupportedOperationException - if the namespace axis is requested and this axis is not supported for this implementation.
Since:
8.4
See Also:
Axis

iterateAxis

public net.sf.saxon.om.AxisIterator iterateAxis(byte axisNumber,
                                                net.sf.saxon.pattern.NodeTest nodeTest)
Return an iteration over all the nodes reached by the given axis from this node that match a given NodeTest

Specified by:
iterateAxis in interface net.sf.saxon.om.NodeInfo
Parameters:
axisNumber - an integer identifying the axis; one of the constants defined in class Axis
nodeTest - A pattern to be matched by the returned nodes; nodes that do not match this pattern are not included in the result
Returns:
a NodeEnumeration that scans the nodes reached by the axis in turn.
Throws:
UnsupportedOperationException - if the namespace axis is requested and this axis is not supported for this implementation.
Since:
8.4
See Also:
Axis

sendNamespaceDeclarations

public void sendNamespaceDeclarations(net.sf.saxon.event.Receiver out,
                                      boolean includeAncestors)
                               throws net.sf.saxon.trans.XPathException
Output all namespace declarations associated with this element. Does nothing if the node is not an element.

This method is primarily for internal use. It should not be considered a stable part of the Saxon API.

Parameters:
out - The relevant Receiver
includeAncestors - True if namespaces declared on ancestor elements must be output; false if it is known that these are
Throws:
net.sf.saxon.trans.XPathException

setSystemId

public void setSystemId(String systemId)
Set the system identifier for this Source.

The system identifier is optional if the source does not get its data from a URL, but it may still be useful to provide one. The application can use a system identifier, for example, to resolve relative URIs and to include in error messages and warnings.

Specified by:
setSystemId in interface Source
Parameters:
systemId - The system identifier as a URL string.

getStringValueCS

public CharSequence getStringValueCS()
Get the string value of the item as a CharSequence. This is in some cases more efficient than the version of the method that returns a String. The method satisfies the rule that X.getStringValueCS().toString() returns a string that is equal to X.getStringValue().

Note that two CharSequence values of different types should not be compared using equals(), and for the same reason they should not be used as a key in a hash table.

If the calling code can handle any CharSequence, this method should be used. If the caller requires a string, the getStringValue() method is preferred.

Specified by:
getStringValueCS in interface net.sf.saxon.om.Item
Specified by:
getStringValueCS in interface net.sf.saxon.om.ValueRepresentation
Returns:
the string value of the item
Since:
8.4
See Also:
getStringValue()

getTypedValue

public net.sf.saxon.om.SequenceIterator getTypedValue()
                                               throws net.sf.saxon.trans.XPathException
Get the typed value of the item.

For a node, this is the typed value as defined in the XPath 2.0 data model. Since a node may have a list-valued data type, the typed value is in general a sequence, and it is returned in the form of a SequenceIterator.

If the node has not been validated against a schema, the typed value will be the same as the string value, either as an instance of xs:string or as an instance of xdt:untypedAtomic, depending on the node kind.

For an atomic value, this method returns an iterator over a singleton sequence containing the atomic value itself.

Specified by:
getTypedValue in interface net.sf.saxon.om.Item
Returns:
an iterator over the items in the typed value of the node or atomic value. The items returned by this iterator will always be atomic values.
Throws:
net.sf.saxon.trans.XPathException - where no typed value is available, for example in the case of an element with complex content
Since:
8.4
