类 ReferenceEscapeChecker

  • 所有已实现的接口:
    proguard.classfile.attribute.visitor.AttributeVisitor, proguard.classfile.constant.visitor.ConstantVisitor, proguard.classfile.instruction.visitor.InstructionVisitor
    public class ReferenceEscapeChecker
extends java.lang.Object
implements proguard.classfile.attribute.visitor.AttributeVisitor, proguard.classfile.instruction.visitor.InstructionVisitor, proguard.classfile.constant.visitor.ConstantVisitor
    This AttributeVisitor can tell whether reference parameters and instances are escaping, are modified, or are returned.
