All Implemented Interfaces:

ImageTransformationContext, UriBasedContext

public class FragmentConcealingContext
extends Object
implements ImageTransformationContext

A decorator which conceals the existence of a specified number of undigested uri fragments (at the end of the fragment list). This can be used to control the maximum number of uri fragments that a digestor can consume. For example the ImageUridigestor will consume everything it can see.
