Class ErrorReportingParseRunner<V>

java.lang.Object

org.parboiled.parserunners.AbstractParseRunner<V>

org.parboiled.parserunners.ErrorReportingParseRunner<V>

All Implemented Interfaces:

MatchHandler, ParseRunner<V>

public class ErrorReportingParseRunner<V>
extends AbstractParseRunner<V>
implements MatchHandler

A ParseRunner implementation that creates an InvalidInputError for the error at a known error location. It never causes the parser to perform more than one parsing run and is rarely used directly. Instead its functionality is relied upon by the ReportingParseRunner and RecoveringParseRunner classes.

ErrorReportingParseRunner

public ErrorReportingParseRunner(Rule rule,
                         int errorIndex)

Creates a new ErrorReportingParseRunner instance for the given rule and the given errorIndex.

Parameters:

rule - the parser rule

errorIndex - the index of the error to report

ErrorReportingParseRunner

public ErrorReportingParseRunner(Rule rule,
                         int errorIndex,
                         MatchHandler inner)

Parameters:

rule - the parser rule

errorIndex - the index of the error to report

inner - another MatchHandler to delegate the actual match handling to, can be null
