Package proguard.evaluation.value

Class RangeValueFactory

java.lang.Object

proguard.evaluation.value.BasicValueFactory

proguard.evaluation.value.ParticularValueFactory

proguard.evaluation.value.BasicRangeValueFactory

proguard.evaluation.value.RangeValueFactory

All Implemented Interfaces:

ValueFactory

public class RangeValueFactory
extends BasicRangeValueFactory
implements ValueFactory

This ValueFactory provides methods to create and reuse IntegerValue instances that have known ranges.

This implementation creates RangeIntegerValue instances in all IntegerValue factory methods. This way, the RangeIntegerValue instances can generalize further to other RangeIntegerValue instances, even if they start out as known particular values.
