Class CheckstyleParserErrorStrategy

java.lang.Object

org.antlr.v4.runtime.DefaultErrorStrategy

org.antlr.v4.runtime.BailErrorStrategy

com.puppycrawl.tools.checkstyle.CheckstyleParserErrorStrategy

All Implemented Interfaces:

org.antlr.v4.runtime.ANTLRErrorStrategy

public class CheckstyleParserErrorStrategy
extends org.antlr.v4.runtime.BailErrorStrategy

Extending BailErrorStrategy allows us to report errors while cancelling the parsing operation. If input is not syntactically correct, we do not need to use antlr's recovery strategy, which can add significant overhead.
