Method Details

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

supportedSince

public NodeVersion supportedSince()

Description copied from interface: ReplicableCommand

Returns a NodeVersion representing the Infinispan version in which this command was added. This value is used to ensure that when the cluster contains different Infinispan versions, only commands compatible with the oldest version are transmitted.

Abstract classes should not implement this method as the version should be specific to an individual implementation. Similarly, implementations which extend another ReplicableCommand should always override this method.

Specified by:

supportedSince in interface ReplicableCommand

Specified by:

supportedSince in interface VersionAware

Overrides:

supportedSince in class RemoveCommand

Returns:

a NodeVersion corresponding to the Infinispan version this command was added.

toString

public String toString()

Overrides:

toString in class RemoveCommand

loadType

public VisitableCommand.LoadType loadType()

Specified by:

loadType in interface VisitableCommand

Overrides:

loadType in class RemoveCommand

Returns:

Nodes on which the command needs to read the previous values of the keys it acts on.
