Class ProfilingParseRunner<V>

java.lang.Object

org.parboiled.parserunners.AbstractParseRunner<V>

org.parboiled.parserunners.ProfilingParseRunner<V>

Type Parameters:

V -

All Implemented Interfaces:

MatchHandler, ParseRunner<V>

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

The ProfilingParseRunner is a special ParseRunner implementation that "watches" a parser digest a number of inputs and collects all sorts of statistical data on the what rules have matched how many times, the number of reincovations of rules at identical input locations, and so on.

The ProfilingParseRunner is typically used during parser debugging and optimization, not in production.
