 public Message(Object dest,
                Object src,
                byte buf[])

Public constructor

Parameters:

dest - Address of receiver. If it is null or a string, then it is sent to the group (either to current group or to the group as given in the string). If it is a Vector, then it contains a number of addresses to which it must be sent. Otherwise, it contains a single destination.

Addresses are generally untyped (all are of type Object. A channel instance must know what types of addresses it expects and downcast accordingly.

src - Address of sender

buf - Message to be sent

 public Message(Object dest,
                Object src,
                Object obj)

Public constructor

Parameters:

dest - Address of receiver. If it is null or a string, then it is sent to the group (either to current group or to the group as given in the string). If it is a Vector, then it contains a number of addresses to which it must be sent. Otherwise, it contains a single destination.

Addresses are generally untyped (all are of type Object. A channel instance must know what types of addresses it expects and downcast accordingly.

src - Address of sender

obj - The object will be serialized into the byte buffer. Object has to be serializable !
