Package org.neo4j.gds.triangle.intersect

Class GraphIntersect<CURSOR extends org.neo4j.gds.api.AdjacencyCursor>

java.lang.Object

org.neo4j.gds.triangle.intersect.GraphIntersect<CURSOR>

All Implemented Interfaces:

org.neo4j.gds.api.RelationshipIntersect

Direct Known Subclasses:

HugeGraphIntersect, UnionGraphIntersect

public abstract class GraphIntersect<CURSOR extends org.neo4j.gds.api.AdjacencyCursor>
extends java.lang.Object
implements org.neo4j.gds.api.RelationshipIntersect

An instance of this is not thread-safe; Iteration/Intersection on multiple threads will throw misleading NullPointerExceptions. Instances are however safe to use concurrently with other RelationshipIterators.
