Class JavaGroups.Header 

java.lang.Object
   |
   +----JavaGroups.Header
public class Header
extends Object
implements Externalizable, Cloneable
Container for header data which is added to the front of a Message by a protocol layer when traveling down the stack. When traveling up on the other side, each protocol layer will remove its Header. Headers can only contain objects, which have to be serializable (or support externalization). Both the object and its byte representation are maintained for faster access of its contents, but the byte buffer is only created when needed (e.g. when Size() or writeExternal() is called) ! .
