Class ErrorLocatingParseRunner<V>

java.lang.Object

org.parboiled.parserunners.AbstractParseRunner<V>

org.parboiled.parserunners.ErrorLocatingParseRunner<V>

All Implemented Interfaces:

MatchHandler, ParseRunner<V>

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

A ParseRunner implementation that creates a simple BasicParseError for the first error found in the input and adds it to the list of ParseErrors. 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.
