IracMetadataRequestCommand

public IracMetadataRequestCommand(ByteString cacheName,
 int segment,
 IracEntryVersion versionSeen)

Method Details

invokeAsync

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

Description copied from interface: CacheRpcCommand

Invoke the command asynchronously.

Specified by:

invokeAsync in interface CacheRpcCommand

Throws:

Throwable

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

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.

toString

public String toString()

Overrides:

toString in class Object

getTopologyId

public int getTopologyId()

Specified by:

getTopologyId in interface TopologyAffectedCommand

setTopologyId

public void setTopologyId(int topologyId)

Specified by:

setTopologyId in interface TopologyAffectedCommand

getCacheName

@ProtoField(1)
public ByteString getCacheName()

Specified by:

getCacheName in interface CacheRpcCommand

Returns:

the name of the cache that produced this command. This will also be the name of the cache this command is intended for.

setOrigin

public void setOrigin(Address origin)

Description copied from interface: CacheRpcCommand

Set the origin of the command

Specified by:

setOrigin in interface CacheRpcCommand

Specified by:

setOrigin in interface ReplicableCommand

Parameters:

origin - the sender's Address

getOrigin

public Address getOrigin()

Description copied from interface: CacheRpcCommand

Get the origin of the command

Specified by:

getOrigin in interface CacheRpcCommand
