Method Detail

getWindowStart

long getWindowStart()

The windowStart is equivalent to the lowest un-received sequenceNumber coming from the receiving end of the connection. It is saying, I have received everything up to one minus this. (Note: it rolls)

extendWindowStart

void extendWindowStart(long wStart)

Extend the windowStart of incoming messages with the full 8 bytes of state

getWindowSpace

int getWindowSpace()

The windowSpace is a measure of how much more data the receiver can receive within its buffer. This number will go to zero if the application on the receiving side is reading data slowly. If it goes to zero then the sender should stop sending.
