invokeAsync
public CompletionStage<?> invokeAsync(ComponentRegistry registry) throws Throwable
Description copied from interface:CacheRpcCommandInvoke the command asynchronously.This method replaces
ReplicableCommand.invoke()for remote execution. The default implementation andReplicableCommand.invoke()will be removed in future versions.- Throws:
Throwable
-
toString
public String toString()
- Overrides:

-
isReturnValueExpected
public boolean isReturnValueExpected()
Description copied from interface:ReplicableCommandIf true, a return value will be provided when performed remotely. Otherwise, a remoteResponseGeneratormay choose to simply return null to save on marshalling costs.- Specified by:
isReturnValueExpectedin interfaceReplicableCommand- Returns:
- true or false
-
getTopologyId
public int getTopologyId()
- Specified by:
getTopologyIdin interfaceTopologyAffectedCommand
-
setTopologyId
public void setTopologyId(int topologyId)
- Specified by:
setTopologyIdin interfaceTopologyAffectedCommand
-
getSegments
public org.infinispan.commons.util.IntSet getSegments()
-
getCommandId
public byte getCommandId()
Description copied from interface:ReplicableCommandUsed by marshallers to convert this command into an id for streaming.- Specified by:
getCommandIdin interfaceReplicableCommand- Returns:
- the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.
-
writeTo
public void writeTo(ObjectOutput output) throws IOException
Description copied from interface:ReplicableCommandWrites this instance to theObjectOutput.- Specified by:
writeToin interfaceReplicableCommand- 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:ReplicableCommandReads this instance from the stream written byReplicableCommand.writeTo(ObjectOutput).- Specified by:
readFromin interfaceReplicableCommand- 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.
