Description copied from interface: Marshaller

A specialized form of RpcDispatcher.Marshaller2.objectToBuffer(Object) that returns an instance of ByteBuffer instead of Buffer.

Specified by:

objectToBuffer in interface Marshaller

Specified by:

objectToBuffer in interface org.jgroups.blocks.RpcDispatcher.Marshaller2

regionalizedMethodCallFromByteBuffer

public RegionalizedMethodCall regionalizedMethodCallFromByteBuffer(byte[] buffer)
                                                            throws java.lang.Exception

Description copied from interface: Marshaller

Returns a RegionalizedMethodCall from a byte buffer. Only use if you know that the byte buffer contains a MethodCall and that you are using region-based marshalling, otherwise use RpcDispatcher.Marshaller.objectFromByteBuffer(byte[])

Description copied from interface: Marshaller

Returns a RegionalizedMethodCall from an object input stream. Only use if you know that the byte buffer contains a MethodCall and that you are using region-based marshalling, otherwise use Marshaller.objectFromObjectStream(java.io.ObjectInputStream)

Specified by:

regionalizedMethodCallFromObjectStream in interface Marshaller

Parameters:

in - object inout stream

Returns:
