Class TouchCommand

java.lang.Object

org.infinispan.commands.read.AbstractDataCommand

org.infinispan.expiration.impl.TouchCommand

All Implemented Interfaces:

DataCommand, FlagAffectedCommand, org.infinispan.commands.remote.CacheRpcCommand, ReplicableCommand, SegmentSpecificCommand, TopologyAffectedCommand, TracedCommand, VisitableCommand, VersionAware

@ProtoTypeId(1237)
public class TouchCommand
extends org.infinispan.commands.read.AbstractDataCommand

This command updates a cache entry's last access timestamp. If eviction is enabled, it will also update the recency information

This command returns a Boolean that is whether this command was able to touch the value or not.

 long flagBitSet,
 boolean touchEvenIfExpired)

Method Details

isTouchEvenIfExpired

public boolean isTouchEvenIfExpired()

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.

Parameters:

ctx - invocation context

visitor - visitor to accept

Returns:

arbitrary return value

Throws:

Throwable - in the event of problems

loadType

public VisitableCommand.LoadType loadType()

Returns:

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

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.

Returns:

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