Class FileImageInputStream

Object
  ImageInputStreamImpl
      FileChannelImageInputStream
          FileImageInputStream

All Implemented Interfaces:

DataInput, ImageInputStream

public class FileImageInputStream
extends FileChannelImageInputStream

An Image Input Stream using a File Channel as the data source. This implementation differs from the Sun's parent implementation in three ways:

• The constructor expects a File argument instead than a FileChannel argument, so no reference to the channel exists outside this class.
• The close() method closes also the channel. This is allowed because this class "own" the channel.
• The file given to the constructor is keep for information purpose.
