Class Stop

java.lang.Object

monq.jfa.AbstractFaAction

monq.jfa.actions.Stop

All Implemented Interfaces:

java.io.Serializable, FaAction

public class Stop
extends AbstractFaAction

implements an FaAction which resets the input of the calling DfaRun to the empty string by calling DfaRun.setIn(null). If the DfaRun's Dfa has not defined an action to invoke at EOF, input processing will stop immediatly after returning from this action.

This action leaves the matching text untouched. To do something with it, consider using a Run action.
