getCommandId
public byte getCommandId()
Description copied from interface:ReplicableCommand
Used by marshallers to convert this command into an id for streaming.- Returns:
- the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.
-
writeTo
public void writeTo(ObjectOutput output) throws IOException
Description copied from interface:ReplicableCommand
Writes this instance to theObjectOutput
.- Parameters:
output
- the stream.- Throws:
IOException
- if an error occurred during the I/O.
-
readFrom
public void readFrom(ObjectInput input) throws IOException, ClassNotFoundException
Description copied from interface:ReplicableCommand
Reads this instance from the stream written byReplicableCommand.writeTo(ObjectOutput)
.- Parameters:
input
- the stream to read.- Throws:
IOException
- if an error occurred during the I/O.ClassNotFoundException
- if it tries to load an undefined class.
-
isForwarded
public boolean isForwarded()
- Overrides:
isForwarded
in classAbstractWriteManyCommand<K,V>
-
setForwarded
public void setForwarded(boolean forwarded)
- Overrides:
setForwarded
in classAbstractWriteManyCommand<K,V>
-
isReturnValueExpected
public boolean isReturnValueExpected()
Description copied from interface:ReplicableCommand
If true, a return value will be provided when performed remotely. Otherwise, a remoteResponseGenerator
may choose to simply return null to save on marshalling costs.- Returns:
- true or false
-
acceptVisitor
public Object acceptVisitor(InvocationContext ctx, Visitor visitor) throws Throwable
Description copied from interface:VisitableCommand
Accept a visitor, and return the result of accepting this visitor.- Parameters:
ctx
- invocation contextvisitor
- visitor to accept- Returns:
- arbitrary return value
- Throws:
Throwable
- in the event of problems
-
perform
public Object perform(InvocationContext ctx) throws Throwable
Description copied from interface:VisitableCommand
Performs the primary function of the command. Please see specific implementation classes for details on what is performed as well as return types. Important: this method will be invoked at the end of interceptors chain. It should never be called directly from a custom interceptor.- Parameters:
ctx
- invocation context- Returns:
- arbitrary return value generated by performing this command
- Throws:
Throwable
- in the event of problems.
-
isSuccessful
public boolean isSuccessful()
Description copied from interface:WriteCommand
Some commands may want to provide information on whether the command was successful or not. This is different from a failure, which usually would result in an exception being thrown. An example is a putIfAbsent() not doing anything because the key in question was present. This would result in a isSuccessful() call returning false.- Specified by:
isSuccessful
in interfaceReplicableCommand
- Specified by:
isSuccessful
in interfaceWriteCommand
- Overrides:
isSuccessful
in classAbstractWriteManyCommand<K,V>
- Returns:
- true if the command completed successfully, false otherwise.
-
isConditional
public boolean isConditional()
Description copied from interface:WriteCommand
Certain commands only work based on a certain condition or state of the cache. For example,ConcurrentMap.putIfAbsent(Object, Object)
only does anything if a condition is met, i.e., the entry in question is not already present. This method tests whether the command in question is conditional or not.- Specified by:
isConditional
in interfaceWriteCommand
- Overrides:
isConditional
in classAbstractWriteManyCommand<K,V>
- Returns:
- true if the command is conditional, false otherwise
-
getAffectedKeys
public Collection<?> getAffectedKeys()
- Returns:
- a collection of keys affected by this write command. Some commands - such as ClearCommand - may return an empty collection for this method.
-
loadType
public VisitableCommand.LoadType loadType()
- Returns:
- Nodes on which the command needs to read the previous values of the keys it acts on.
-
getKeysToLock
public Collection<?> getKeysToLock()
Description copied from interface:RemoteLockCommand
It returns aCollection
with the keys to be lock.It may return an empty collection if no keys needs to be locked independently of the return value of
RemoteLockCommand.hasSkipLocking()
. It may contains duplicated keys andnull
is not a valid return value.- Returns:
- a
Collection
of keys to lock.

init
public void init(ComponentRegistry componentRegistry)
