Class Neo4jDistanceWithMetrics

java.lang.Object

org.evomaster.client.java.controller.internal.db.neo4j.Neo4jDistanceWithMetrics

public final class Neo4jDistanceWithMetrics
extends Object

Result of scoring one captured Cypher query against the live graph: the distance to satisfying the query, how many graph nodes were considered, and whether the evaluation failed.

The distance is 1 - ofTrue of the Truthness computed by the heuristics calculator, so a computed value lies in [0,1] by construction, with 0 meaning the query is satisfied. A failed evaluation carries Neo4jHeuristicsCalculator.MAX_NEO4J_DISTANCE.

Constructor Details

Neo4jDistanceWithMetrics

public Neo4jDistanceWithMetrics(double distance,
 int numberOfEvaluatedNodes,
 boolean evaluationFailure)

Creates a Neo4j heuristic result.

Parameters:

distance - distance to satisfying the query, 0 meaning satisfied

numberOfEvaluatedNodes - number of graph nodes considered

evaluationFailure - whether the evaluation failed, in which case the distance must be Neo4jHeuristicsCalculator.MAX_NEO4J_DISTANCE

Method Details

public double getDistance()

Returns:

distance to satisfying the query, 0 meaning satisfied, Neo4jHeuristicsCalculator.MAX_NEO4J_DISTANCE on failure

getNumberOfEvaluatedNodes

public int getNumberOfEvaluatedNodes()

Returns:

number of graph nodes considered

isEvaluationFailure

public boolean isEvaluationFailure()

Returns:

whether the evaluation failed
