java.lang.Object

org.evomaster.client.java.controller.neo4j.heuristics.CypherConditionRenamer

public final class CypherConditionRenamer
extends Object

Deep-clones a CypherCondition (or Operand) while substituting the variable names it refers to, according to a rename map. Used by Neo4jPatternExpander when it clones a variable-length edge into a chain: the edge's type/property conditions and the endpoints' labels must be re-bound to the fresh variable names of the cloned edges and intermediate nodes.

Only variable names change; operators, literals and structure are preserved. A name not present in the map is left unchanged.

Method Summary

Modifier and Type	Method	Description

Method Details

rename

public static CypherCondition rename(CypherCondition c,
 Map<String,String> renames)

rename

public static Operand rename(Operand o,
 Map<String,String> renames)

referencesVariable

public static boolean referencesVariable(CypherCondition c,
 String variable)

True when the condition references variable as a node/edge variable. Used to decide which endpoint conditions an intermediate node should inherit.
