Examples of com.hp.hpl.jena.gvs.impl.FCAGraphImpl

com.hp.hpl.jena.gvs.impl.FCAGraphImpl
This class implements FCAGraph, it does decomposition and reconstruction of the graph as needed. Once a decomposition or a reconstruction is created both graph and decomposition are kept in memory. Instances of this class are inmutable. When an instance is accessed as a Jena Graph a mapping from org.wymiwyg.rdf.graphs.NodeS to com.hp.hpl.jena.graph.NodeS is made. @author reto
