类 ParameterUsageMarker

  • 所有已实现的接口:
    proguard.classfile.attribute.visitor.AttributeVisitor, proguard.classfile.instruction.visitor.InstructionVisitor, proguard.classfile.visitor.MemberVisitor
    public class ParameterUsageMarker
extends java.lang.Object
implements proguard.classfile.visitor.MemberVisitor, proguard.classfile.attribute.visitor.AttributeVisitor, proguard.classfile.instruction.visitor.InstructionVisitor
    This MemberVisitor counts the parameters and marks the used parameters of the methods that it visits. It also marks the 'this' parameters of methods that have hierarchies.
