,ParseRunner<V>
public class ErrorLocatingParseRunner<V> extends AbstractParseRunner<V> implements MatchHandler
AParseRunner
implementation that creates a simpleBasicParseError
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 theReportingParseRunner
andRecoveringParseRunner
classes.
