ucar.jpeg.jj2000.j2k.image.DataBlkInt
This class provides default implementation of the methods in the 'InvWT' interface. The source is always a 'MultiResImgData', which is a multi-resolution image. The default implementation is just to return the value of the source at the current image resolution level, which is set by the 'setImgResLevel()' method.
This abstract class can be used to facilitate the development of other classes that implement the 'InvWT' interface, because most of the trivial methods are already implemented.

If the default implementation of a method provided in this class does not suit a particular implementation of the 'InvWT' interface, the method can be overriden to implement the proper behaviour.

If the 'setImgResLevel()' method is overriden then it is very important that the one of this class is called from the overriding method, so that the other methods in this class return the correct values.
