de.grogra.rgg
Class BooleanSynth<T>

java.lang.Object
  de.grogra.rgg.BooleanSynth<T>

Type Parameters:

T - the type of objects for which synthesized attributes are computed

All Implemented Interfaces:

VoidToBooleanGenerator

public final class BooleanSynth<T>
extends java.lang.Object
implements VoidToBooleanGenerator

Instances of BooleanSynth are used in the context of the method Library.synthesize(Object, ObjectToObjectGenerator, ObjectToBoolean). and represent the information needed for the computation of a synthesized attribute: object is the current object for which the synthesized attribute has to be computed, the generator method evaluateBoolean yields the values of the synthesized attributes of object's descendants.

Method Detail

evaluateBoolean

public void evaluateBoolean(BooleanConsumer cons)

This generator method yields the values of the synthesized attribute for every descendant of object. These values have been computed previously.

Specified by:

evaluateBoolean in interface VoidToBooleanGenerator

Parameters:

cons - the consumer which receives the values of synthesized attribute of descendants

get

public boolean get(int index)

size

public int size()

values

public void values(BooleanConsumer cons)

This method is an alias for evaluateBoolean(de.grogra.xl.lang.BooleanConsumer).
