process

public boolean process(byte value)
                throws Exception

Specified by:

process in interface ByteProcessor

Returns:

true if the processor wants to continue the loop and handle the next byte in the buffer. false if the processor wants to stop handling bytes and abort the loop.

Throws:

Exception
