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`
