| MultiResImgDataAdapter | | abstract public class MultiResImgDataAdapter implements MultiResImgData(Code) | | This class provides a default implementation for the methods of the
'MultiResImgData' interface. The default implementation consists just in
returning the value of the source, where the source is another
'MultiResImgData' object.
This abstract class can be used to facilitate the development of other
classes that implement 'MultiResImgData'. For example a dequantizer can
inherit from this class and all the trivial methods do not have to be
reimplemented.
If the default implementation of a method provided in this class does
not suit a particular implementation of the 'MultiResImgData' interface,
the method can be overriden to implement the proper behaviour.
