SunWritableRaster

Class Overview

This class exists as a middle layer between WritableRaster and its implementation specific subclasses (ByteComponentRaster, ShortBandedRaster, etc). It provides utilities to steal the data arrays from the standard DataBuffer types and also steals the StateTrackableDelegate from the associated DataBuffer so that it can be updated when the data is changed.
