Class TouchCommand

java.lang.Object

org.infinispan.commands.remote.BaseRpcCommand

org.infinispan.expiration.impl.TouchCommand

All Implemented Interfaces:

CacheRpcCommand, ReplicableCommand, TopologyAffectedCommand

public class TouchCommand
extends BaseRpcCommand
implements TopologyAffectedCommand

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.

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

Returns:

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

isReturnValueExpected

public boolean isReturnValueExpected()

Description copied from interface: ReplicableCommand

If true, a return value will be provided when performed remotely. Otherwise, a remote ResponseGenerator may choose to simply return null to save on marshalling costs.

Specified by:

isReturnValueExpected in interface ReplicableCommand

Returns:

true or false

writeTo

public void writeTo(ObjectOutput output)
             throws IOException

Description copied from interface: ReplicableCommand

Writes this instance to the ObjectOutput.

Specified by:

writeTo in interface ReplicableCommand

Parameters:

output - the stream.

Throws:

IOException - if an error occurred during the I/O.

readFrom

public void readFrom(ObjectInput input)
              throws IOException,
                     ClassNotFoundException

Description copied from interface: ReplicableCommand

Reads this instance from the stream written by ReplicableCommand.writeTo(ObjectOutput).

Specified by:

readFrom in interface ReplicableCommand

Parameters:

input - the stream to read.

Throws:

IOException - if an error occurred during the I/O.

ClassNotFoundException - if it tries to load an undefined class.

getTopologyId

public int getTopologyId()

Specified by:

getTopologyId in interface TopologyAffectedCommand

setTopologyId

public void setTopologyId(int topologyId)

Specified by:

setTopologyId in interface TopologyAffectedCommand

invokeAsync

public CompletionStage<Object> invokeAsync(ComponentRegistry componentRegistry,
                                           long currentTimeMilli)

invokeAsync

public CompletionStage<?> invokeAsync(ComponentRegistry componentRegistry)

Description copied from interface: CacheRpcCommand

Invoke the command asynchronously.

This method replaces ReplicableCommand.invoke() for remote execution. The default implementation and ReplicableCommand.invoke() will be removed in future versions.

Specified by:

invokeAsync in interface CacheRpcCommand
