Constructor Detail

EvictCommand

public EvictCommand(Object key,
                    CacheNotifier notifier,
                    Set<Flag> flags,
                    CommandInvocationId commandInvocationId,
                    InternalEntryFactory factory)

Method Detail

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 RemoveCommand

Parameters:

ctx - invocation context

visitor - 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: ReplicableCommand

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.

Specified by:

perform in interface ReplicableCommand

Overrides:

perform in class RemoveCommand

Parameters:

ctx - invocation context

Returns:

arbitrary return value generated by performing this command

Throws:

Throwable - in the event of problems.

notify

public void notify(InvocationContext ctx,
                   Object value,
                   Metadata previousMetadata,
                   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

readsExistingValues

public boolean readsExistingValues()

Specified by:

readsExistingValues in interface VisitableCommand

Overrides:

readsExistingValues in class RemoveCommand

Returns:

true if the command needs to read the previous values of the keys it acts on.
