Class QuantifiedPathPattern

java.lang.Object

org.evomaster.client.java.controller.neo4j.operations.QuantifiedPathPattern

public class QuantifiedPathPattern
extends Object

A quantified path pattern (QPP), i.e. a sub-pattern repeated a number of times, such as ((a)-[:KNOWS]->(b)){1,3}.
Unlike a variable-length relationship (*1..3), which repeats a single edge, a QPP repeats an entire MatchPattern (multiple nodes and edges, and possibly nested QPPs). The repetition bounds are [min, max], where a null max means unbounded (+ or *).
The labels, relationship types, properties and inline WHERE that constrain the sub-pattern are kept in getConditions(), scoped to this QPP rather than mixed into the outer operation's list — so when the calculator expands the repetition it can clone the sub-pattern's conditions per hop.

 List<CypherCondition> conditions,
 int min,
 Integer max)

Method Details

getSubPattern

public MatchPattern getSubPattern()

getConditions

public List<CypherCondition> getConditions()

Returns the conditions scoped to this sub-pattern (labels, relationship types, properties, inline WHERE), in source order. Empty when the sub-pattern is purely structural.

getMin

public int getMin()

getMax

public Integer getMax()

isUnboundedMax

public boolean isUnboundedMax()

toString

public String toString()
