Class ClusteredGetCommand

java.lang.Object

org.infinispan.commands.remote.BaseRpcCommand

org.infinispan.commands.remote.BaseClusteredReadCommand

org.infinispan.commands.remote.ClusteredGetCommand

All Implemented Interfaces:

CacheRpcCommand, ReplicableCommand, SegmentSpecificCommand, TopologyAffectedCommand, TracedCommand, VersionAware

@ProtoTypeId(1059)
public class ClusteredGetCommand
extends BaseClusteredReadCommand
implements SegmentSpecificCommand

Issues a remote get call. This is not a VisitableCommand and hence not passed up the interceptor chain.

ClusteredGetCommand

public ClusteredGetCommand(Object key,
 ByteString cacheName,
 Integer segment,
 long flags)

Method Details

getSegment

public int getSegment()

Description copied from interface: SegmentSpecificCommand

Returns the segment that this key maps to. This must always return a number 0 or larger.

Specified by:

getSegment in interface SegmentSpecificCommand

Returns:

the segment of the key

invokeAsync

public CompletionStage<?> invokeAsync(ComponentRegistry componentRegistry)
                               throws Throwable

Invokes a logical "get(key)" on a remote cache and returns results.

Specified by:

invokeAsync in interface CacheRpcCommand

Returns:

Throws:

Throwable

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

Returns:

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