Method Detail

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 InvalidateCommand

Returns:

the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.

init

public void init(Configuration config,
                 DistributionManager dm,
                 CacheNotifier n,
                 DataContainer dc)

perform

public Object perform(InvocationContext ctx)
               throws Throwable

Description copied from class: InvalidateCommand

Performs an invalidation on a specified entry

Specified by:

perform in interface ReplicableCommand

Overrides:

perform in class InvalidateCommand

Parameters:

ctx - invocation context

Returns:

null

Throws:

Throwable - in the event of problems.

setKeys

public void setKeys(Object[] keys)

shouldInvoke

public boolean shouldInvoke(InvocationContext ctx)

Description copied from interface: VisitableCommand

Used by the InboundInvocationHandler to determine whether the command should be invoked or not.

Specified by:

shouldInvoke in interface VisitableCommand

Overrides:

shouldInvoke in class AbstractDataCommand

Returns:

true if the command should be invoked, false otherwise.

equals

public boolean equals(Object o)

Overrides:

equals in class InvalidateCommand

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

Overrides:

getParameters in class InvalidateCommand

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

Overrides:

setParameters in class InvalidateCommand

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

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.

Specified by:

acceptVisitor in interface VisitableCommand

Overrides:

acceptVisitor in class InvalidateCommand

Parameters:

ctx - invocation context

visitor - visitor to accept

Returns:

arbitrary return value

Throws:

Throwable - in the event of problems
