Detailed Description

Specialization of the base TAO_Transport class to handle the server side MIOP protocol.

Member Typedef Documentation

Complete packets.

Constructor & Destructor Documentation

TAO_UIPMC_Mcast_Transport::TAO_UIPMC_Mcast_Transport ( TAO_UIPMC_Mcast_Connection_Handler handler,
TAO_ORB_Core orb_core 
)

Constructor.

TAO_UIPMC_Mcast_Transport::~TAO_UIPMC_Mcast_Transport ( void  )

Default destructor.

Member Function Documentation

void TAO_UIPMC_Mcast_Transport::cleanup_packets ( bool  expired_only)
private

Cleanup either all packets or expired only depending the expired_only flag.

TAO_Connection_Handler * TAO_UIPMC_Mcast_Transport::connection_handler_i ( void  )
protectedvirtual

@TODO: These methods IMHO should have more meaningful names. The names seem to indicate nothing. Shouldn't ever be called on the server side.

Implements TAO_Transport.

ACE_Event_Handler * TAO_UIPMC_Mcast_Transport::event_handler_i ( void  )
protectedvirtual

@TODO: These methods IMHO should have more meaningful names. The names seem to indicate nothing. Shouldn't ever be called on the server side.

Implements TAO_Transport.

int TAO_UIPMC_Mcast_Transport::handle_input ( TAO_Resume_Handle rh,
ACE_Time_Value max_wait_time = 0 
)
virtual

Look for the documentation in Transport.h.

Reimplemented from TAO_Transport.

ssize_t TAO_UIPMC_Mcast_Transport::recv ( char *  ,
size_t  ,
ACE_Time_Value const *   
)
protectedvirtual

Shouldn't ever be called. We use recv_all() with different semantics.

Implements TAO_Transport.

TAO_PG::UIPMC_Recv_Packet * TAO_UIPMC_Mcast_Transport::recv_all ( TAO_Resume_Handle rh)
private

Return the next complete MIOP packet, possiably dequeueing as many as are available first from the socket.

char * TAO_UIPMC_Mcast_Transport::recv_packet ( char *  buf,
size_t  len,
ACE_INET_Addr from_addr,
CORBA::UShort packet_length,
CORBA::ULong packet_number,
bool &  stop_packet,
u_long &  id_hash 
) const
private

Receive a UDP message and extract all necessary info from the MIOP header. If everything is fine return a pointer to the first byte of the non-MIOP data.

int TAO_UIPMC_Mcast_Transport::register_handler ( void  )
protectedvirtual

@TODO: These methods IMHO should have more meaningful names. The names seem to indicate nothing. Shouldn't ever be called on the server side.

Reimplemented from TAO_Transport.

ssize_t TAO_UIPMC_Mcast_Transport::send ( iovec *  ,
int  ,
size_t &  ,
ACE_Time_Value const *   
)
protectedvirtual

Write the complete Message_Block chain to the connection. Shouldn't ever be called on the server side.

Implements TAO_Transport.

int TAO_UIPMC_Mcast_Transport::send_message ( TAO_OutputCDR ,
TAO_Stub = 0,
TAO_ServerRequest = 0,
TAO_Message_Semantics  = TAO_Message_Semantics (),
ACE_Time_Value = 0 
)
virtual

Shouldn't ever be called on the server side.

Implements TAO_Transport.

int TAO_UIPMC_Mcast_Transport::send_request ( TAO_Stub ,
TAO_ORB_Core ,
TAO_OutputCDR ,
TAO_Message_Semantics  ,
ACE_Time_Value  
)
virtual

@TODO: These methods IMHO should have more meaningful names. The names seem to indicate nothing. Shouldn't ever be called on the server side.

Implements TAO_Transport.
