public AbstractTransactionCommand()

perform

public Object perform(InvocationContext ctx)

Default implementation which is a no-op. Transaction boundary commands always return a null.

Specified by:

perform in interface ReplicableCommand

Parameters:

ctx - invocation context

Returns:

null

getGlobalTransaction

public GlobalTransaction getGlobalTransaction()

setGlobalTransaction

public void setGlobalTransaction(GlobalTransaction gtx)

getParameters

public Object[] getParameters()

Description copied from interface: ReplicableCommand

Used by marshallers to stream this command across a network

Specified by:

getParameters in interface ReplicableCommand

Returns:

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

setParameters

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

Description copied from interface: ReplicableCommand

Used by the CommandsFactory to create a command from raw data read off a stream.

Specified by:

setParameters in interface ReplicableCommand

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

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString
