详细描述

Helper class for vrpn_Connection that automates redundant transmission for unreliable (low-latency) messages. Call pack_messages() here instead of on your connection, and call mainloop() here before calling mainloop() on your connection.

成员函数说明

mainloop()

virtual void mainloop ( void )

virtual

Determines which messages need to be resent and queues them up on the connection for transmission.

pack_message()

virtual int pack_message ( vrpn_uint32 len, timeval time, vrpn_uint32 type, vrpn_uint32 sender, const char * buffer, vrpn_uint32 class_of_service, vrpn_int32 numRetransmissions = -1, timeval * transmissionInterval = NULL )

virtual

If !isEnabled(), does a normal pack_message(), but if isEnabled() ignores class_of_service and sends it vrpn_CONNECTION_LOW_LATENCY, sending it an additional number of times equal to numRetransmissions at minimum intervals of transmissionInterval. Specify -1 and NULL to use default values.

setDefaults()

virtual void setDefaults ( vrpn_uint32 numRetransmissions, timeval transmissionInterval )

virtual

Set default values for future calls to pack_message().

类成员变量说明

d_numMessagesQueued

vrpn_uint32 d_numMessagesQueued

protected

For debugging, mostly.
