public abstract class MultiResImgDataAdapter
This class provides a default implementation of the methods in the 'MultiResImgData' interface. The default implementation is just to return 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.
