Method Detail

process

protected boolean process(int bytesToEat)
                   throws java.io.IOException

Process the marker segment. The DataInputStream will be at the point of having read the marker code. The process method must consume exactly the number of bytes remaining in the marker segment.

Specified by:

process in class MarkerSegment

Parameters:

bytesToEat - The number of bytes that must be consumed. If it is 0 for a MarkerSegment, the number of bytes to consume is unknown.

Returns:

true if segment is well-formed, false otherwise.

Throws:

java.io.IOException
