Class CachedEdge

java.lang.Object

org.mindswap.pellet.tableau.cache.CachedEdge

All Implemented Interfaces:

Edge

Direct Known Subclasses:

CachedInEdge, CachedOutEdge

public abstract class CachedEdge
extends Object
implements Edge

Title:

Description: Represents an edge cached for a CachedNode. A cached edge stores the information about only one node (the neighbor of the cached node where this edge is stored) and for that node only the name is stored. This keeps the memory footprint of cached nodes to a minimum without causing any slow downs (since cached nodes are used only in limited ways).
