com.sun.media.imageio.stream.FileChannelImageOutputStream

A class which implements ImageOutputStream using a FileChannel as the eventual data destination.

Memory mapping is used for reading and direct buffers for writing. Only methods which provide significant performance improvement with respect to the superclass implementation are overridden. Overridden methods are not commented individually unless some noteworthy aspect of the implementation must be described.

The methods of this class are not synchronized.
