public abstract class MultiResImgDataAdapter extends Object implements MultiResImgData
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.
