public Object perform(InvocationContext ctx)
               throws Throwable
Performs an invalidation on a specified entry

Specified by:
perform in interface ReplicableCommand
Overrides:
perform in class RemoveCommand
Parameters:
ctx - invocation context
Returns:
null
Throws:
Throwable - in the event of problems.

invalidate

protected void invalidate(InvocationContext ctx,
                          Object keyToInvalidate)
                   throws Throwable
Throws:
Throwable

                      Object value,
                      boolean isPre)
Overrides:
notify in class RemoveCommand

getCommandId

public byte getCommandId()
Description copied from interface: ReplicableCommand
Used by marshallers to convert this command into an id for streaming.

Specified by:
getCommandId in interface ReplicableCommand
Overrides:
getCommandId in class RemoveCommand
Returns:
the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.

toString

public String toString()
Overrides:
toString in class RemoveCommand

getParameters

public Object[] getParameters()
Description copied from interface: ReplicableCommand
Used by marshallers to stream this command across a network

Specified by:

an object array of arguments, compatible with pre-2.2.0 MethodCall args.

setParameters

public void setParameters(int commandId,
                          Object[] args)

Specified by:
setParameters in interface ReplicableCommand
Overrides:
setParameters in class AbstractDataCommand
Parameters:
commandId - command id to set. This is usually unused but *could* be used in the event of a command having multiple IDs, such as PutKeyValueCommand.
args - object array of args
