Class DynamicMemberReferenceInitializer

java.lang.Object

proguard.classfile.util.SimplifiedVisitor

proguard.classfile.util.DynamicMemberReferenceInitializer

All Implemented Interfaces:

ConstantVisitor, InstructionVisitor, MemberVisitor

public class DynamicMemberReferenceInitializer
extends SimplifiedVisitor
implements InstructionVisitor, ConstantVisitor, MemberVisitor

This InstructionVisitor initializes any constant Class.get[Declared]{Field,Method} references of all instructions it visits. More specifically, it fills out the references of string constant pool entries that refer to a class member in the program class pool or in the library class pool.

It optionally prints notes if on usage of (SomeClass)Class.forName(variable).newInstance().

The class hierarchy and references must be initialized before using this visitor.
