Class RDFEngineDecorator<X extends RDFEngine>

java.lang.Object

org.aksw.jenax.dataaccess.sparql.factory.dataengine.RDFEngineDecorator<X>

public class RDFEngineDecorator<X extends RDFEngine>
extends Object

A wrapper for an RDFEngine that supports applying transformations on several levels. The levels are: link source, link, algebra and expression. Internally, transformation builders are used to group transformations on the same level such to minimize the amount of needed (un-)wrapping.
