Class Cypher25AntlrParser

java.lang.Object

org.evomaster.client.java.controller.neo4j.parser.cypher25.Cypher25AntlrParser

All Implemented Interfaces:

CypherParser

public class Cypher25AntlrParser
extends Object
implements CypherParser

CypherParser implementation built on the official Neo4j Cypher25 ANTLR grammar. Because the grammar is the one Neo4j itself uses, any query this parser accepts is guaranteed to be valid Cypher.
Syntax errors are not swallowed: the lexer and parser are wired with a listener that fails fast, and the error (with line/column) is surfaced as a CypherParserException.
