public class ObjectTable
A lookup table for objects. This implementation is not synchronized, it is up to the caller to synchronize it properly.
Constructor Summary | |
---|---|
ObjectTable()
Creates a new table. |
|
ObjectTable(int increment)
Creates a new table. |
|
ObjectTable(int rowIncrement,
int colIncrement)
Creates a new table. |
Method Summary | |
---|---|
void |
clear()
Clears the table. |
protected void |
copyColumn(int oldColumn,
int newColumn)
Copys the contents of the old column to the new column. |
protected void |
copyRow(int oldRow,
int newRow)
Copys the contents of the old row to the new row. |
void |
ensureCapacity(int row,
int column)
Ensures that there is storage capacity for the specified item. |
protected void |
ensureRowCapacity(int row)
Checks that there is storage capacity for the specified row and resizes if necessary. |
boolean |
equals(Object o)
Tests this paint table for equality with another object (typically also an ObjectTable ). |
int |
getColumnCount()
Returns the number of columns in the table. |
int |
getColumnIncrement()
Returns the column size increment. |
protected Object[][] |
getData()
Returns the table data. |
protected Object |
getObject(int row,
int column)
Returns the object from a particular cell in the table. |
int |
getRowCount()
Returns the number of rows in the table. |
int |
getRowIncrement()
Returns the row size increment. |
int |
hashCode()
Returns a hash code value for the object. |
protected Object |
readSerializedData(ObjectInputStream stream)
Handles the deserialization of a single element of the table. |
protected void |
setData(Object[][] data,
int colCount)
Sets the table data. |
protected void |
setObject(int row,
int column,
Object object)
Sets the object for a cell in the table. |
protected void |
writeSerializedData(ObjectOutputStream stream,
Object o)
Handles the serialization of an single element of this table. |
