Class Neo4jNode

java.lang.Object

org.evomaster.client.java.controller.neo4j.data.Neo4jNode

public class Neo4jNode
extends Object

A node of a captured Neo4j graph, used as the G side when computing the heuristic H(Q, G). It is the in-memory counterpart of a stored node: a stable id (the driver's elementId), the set of labels, and the property map.

This is a plain data holder built either by hand (tests) or by reading the live database; it has no relation to PatternNode, which is the structural node of a parsed query pattern.
