## Detailed Description

Local representation for remote peers.

Both senders and receivers in the multicast group need to maintain explicit representations of their "peers". For example, a sender needs to know the list of all the receivers and what messages they have reported as successfully received. Likewise, the receiver needs to maintain separate state for each remote sender, and must be able to disconnect from all of them gracefully when needed. The RMCast_Proxy class is an opaque representation of such a peer, and hides all the networking details from the rest of the system.

## Constructor & Destructor Documentation

ACE_INLINE ACE_RMCast_Proxy::ACE_RMCast_Proxy ( | void )

| Constructor.

ACE_RMCast_Proxy::~ACE_RMCast_Proxy ( | void )`[virtual]`

| Destructor.

## Member Function Documentation

int ACE_RMCast_Proxy::ack ( | ACE_RMCast::Ack & ack )`[virtual]`

| Proxies process the ACK sequence numbers to cache the ack information from the peer. Reimplemented from ACE_RMCast_Module.

ACE_UINT32 ACE_RMCast_Proxy::highest_received ( | void ) const`[virtual]`

| Return the highest sequence number successfully received. Only applies to remote receiver proxies. Please read the documentation in ACE_RMCast::Ack

ACE_UINT32 ACE_RMCast_Proxy::next_expected ( | void ) const`[virtual]`

| Return the next sequence number expected by the peer. Only applies to remote receiver proxies. Please read the documentation in ACE_RMCast::Ack

int ACE_RMCast_Proxy::reply_ack ( | ACE_RMCast::Ack & ack )`[pure virtual]`

| Reimplemented in ACE_RMCast_UDP_Proxy.

int ACE_RMCast_Proxy::reply_ack_join ( | ACE_RMCast::Ack_Join & ack_join )`[virtual]`

| Reimplemented in ACE_RMCast_UDP_Proxy.

int ACE_RMCast_Proxy::reply_ack_leave ( | ACE_RMCast::Ack_Leave & ack_leave )`[pure virtual]`

| Reimplemented in ACE_RMCast_UDP_Proxy.

int ACE_RMCast_Proxy::reply_data ( | ACE_RMCast::Data & data )`[pure virtual]`

| Send messages directly to the peer. Send a message directly to the peer, i.e. the message is not sent through the multicast group and it may not be processed by all the layers in the stack. Reimplemented in ACE_RMCast_UDP_Proxy.

int ACE_RMCast_Proxy::reply_join ( | ACE_RMCast::Join & join )`[pure virtual]`

| Reimplemented in ACE_RMCast_UDP_Proxy.

int ACE_RMCast_Proxy::reply_leave ( | ACE_RMCast::Leave & leave )`[pure virtual]`

| Reimplemented in ACE_RMCast_UDP_Proxy.

int ACE_RMCast_Proxy::reply_poll ( | ACE_RMCast::Poll & poll )`[pure virtual]`

| Reimplemented in ACE_RMCast_UDP_Proxy.
