Method Detail

initialize

public void initialize(BuddyManager buddyManager,
                       InterceptorChain invoker,
                       TransactionTable transactionTable,

perform

public Object perform(InvocationContext ctx)
               throws Throwable
Performs a cleanup on nodes that would have been previously gravitated away from the current cache instance.

Specified by:
perform in interface ReplicableCommand
Parameters:
ctx - invocation context
Returns:
arbitrary return value generated by performing this command
Throws:
Throwable - in the event of problems.

getCommandId

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

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

getBackup

public Fqn getBackup()

getGlobalTransaction

public GlobalTransaction getGlobalTransaction()

setGlobalTransaction

public void setGlobalTransaction(GlobalTransaction gtx)

getFqn

public Fqn getFqn()

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

public String toString()
Overrides:
toString in class Object
