public members:

GPipe( GPipe &input)

Copy constructorTakes the source, destination, and optionally the flow and capacity as arguments

~GPipe()

Destructor, frees the message queues

GPipe & operator=( GPipe &input)

Duplicates the pipe and its message queues

void Reset()

void Print()

int GetSource()

Returns the source of the pipe

int GetDest()

private members:

GQueue < GMessage > out_queue[2]
