consume

public void consume(ByteCursor cursor)

This method will not consume any bytes from the cursor. This ensures that the next byte read from the stream is the first character of the next HTTP message within the pipeline.

Specified by:

consume in interface ByteConsumer

Parameters:

cursor - this is the cursor which will not be read from

isFinished
