getCommandId
public byte getCommandId()
Description copied from interface:ReplicableCommand
Used by marshallers to convert this command into an id for streaming.- 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 remoteResponseGenerator
may choose to simply return null to save on marshalling costs.- Specified by:
isReturnValueExpected
in interfaceReplicableCommand
- Overrides:
isReturnValueExpected
in classorg.infinispan.commands.read.AbstractDataCommand
- Returns:
- true or false
-
writeTo
public void writeTo(ObjectOutput output) throws IOException
Description copied from interface:ReplicableCommand
Writes this instance to theObjectOutput
.- Parameters:
output
