monq.jfa.actions

Class Run

java.lang.Object

monq.jfa.AbstractFaAction

monq.jfa.actions.Run

All Implemented Interfaces:

java.io.Serializable, FaAction

public class Run
extends AbstractFaAction

runs several FaAction objects, one after another.

Objects of this class contain a sequence of client FaActions which are run one after another when invoke() is called. The first action in the sequence will see the original TextStore object as prepared by the calling DfaRun. The second and further client actions will get passed a TextStore which contains only one part, namely the text resulting from the application of the previous actions. The resulting text in the output will be exactly what the last action leaves there.

The callback may change the whole of yytext, but the under most circumstances, only the matching text should be changed. Parameter runner is the DfaRun object which called this function. Of interest are its fields DfaRun.clientData and DfaRun.collect.
