详细描述

Helper class that eliminates duplicates; only the first instance of a message is delivered. Registers a callback on connection for any type it's told to monitor; when it gets a message back, checks its list of recently-seen-timestamps for that type; if it isn't on the list, it's dispatched and replaces the oldest item on the list. List length is limited, so if too many messages of the same type (more than VRPN_RR_LENGTH) are interleaved - if transmissionInterval * numRetransmissions > VRPN_RR_LENGTH * the normal rate of message generation - it will not detect the redundant messages.

成员函数说明

clearMemory()

void clearMemory

(

void

)

Throws away / resets statistics.

record()

void record

(

vrpn_bool

)

Turns "memory" (tracking statistics of redundant reception) on and off.

writeMemory()

void writeMemory

(

const char *

filename

)

Writes statistics to the named file: timestamp of every message received and number of copies of that message. Detects partial losses, but not when all copies are lost, since vrpn_RR doesn't expect messages.
