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.
