Detailed Description

Keep track of the receiver module.

A receiver proxy must reject invalid messages and communicate with the sender to join and leave the multicast group.

This module performs all the task related to

Member Enumeration Documentation

enum ACE_RMCast_Receiver_Module::Receiver_State

Simple enum used to describe the receiver state transitions. Receivers go through several states before they can fully accept messages, the following comments describe those states, as well as the possible transitions This configuration is pesimistic, any invalid message is cause enough to reclaim all the resources. This partially addresses situations where either accidentally or intentionally a sender is multicasting packets to the wrong group.
