typedef ACE_Hash_Map_Manager<ACE_INET_Addr,ACE_RMCast_UDP_Proxy*,ACE_Null_Mutex> ACE_RMCast_IO_UDP::Map [private]

Use a Hash_Map to maintain the collection of proxies.

Constructor & Destructor Documentation

ACE_INLINE ACE_RMCast_IO_UDP::ACE_RMCast_IO_UDP ( ACE_RMCast_Module_Factory * factory )

Constructor.
The <factory> argument is used to create the modules for each proxy that process incoming messages. The class does *not* assume ownership of <factory>, the caller owns it. But it does assume ownership of the modules returned by the factory, and it may ask the factory to release them eventually.

ACE_RMCast_IO_UDP::~ACE_RMCast_IO_UDP ( void )

Destructor.

Member Function Documentation

int ACE_RMCast_IO_UDP::ack ( ACE_RMCast::Ack & ) [virtual]

Push an ack mesage through the stack.

Reimplemented from ACE_RMCast_Module.

int ACE_RMCast_IO_UDP::ack_join ( ACE_RMCast::Ack_Join & ) [virtual]

Push a message to ack a join request through the stack.

Reimplemented from ACE_RMCast_Module.

int ACE_RMCast_IO_UDP::ack_leave ( ACE_RMCast::Ack_Leave & ) [virtual]

Push a message to ack a leave request through the stack.

Reimplemented from ACE_RMCast_Module.

ACE_INLINE ACE_RMCast_UDP_Proxy * ACE_RMCast_IO_UDP::allocate_and_bind_proxy ( ACE_RMCast_Module * module,

const ACE_INET_Addr &

) [private]

int ACE_RMCast_IO_UDP::data ( ACE_RMCast::Data & ) [virtual]

Push data through the stack.

Reimplemented from ACE_RMCast_Module.

ACE_HANDLE ACE_RMCast_IO_UDP::get_handle ( void ) const

Obtain the handle for the underlying socket.

int ACE_RMCast_IO_UDP::handle_events ( ACE_Time_Value * tv = 0 )

)

Open the internal socket, but only to send multicast data.
It is not clear to me if this is a valid configuration. Maybe it would be a problem to expose two separate, incompatible interfaces (check the subscribe() method). However, the alternative would be to implement almost identical class for outgoing and incoming UDP I/O
