Class DynamicClassReferenceInitializer

java.lang.Object

proguard.classfile.util.SimplifiedVisitor

proguard.classfile.util.DynamicClassReferenceInitializer

All Implemented Interfaces:

AttributeVisitor, ConstantVisitor, InstructionVisitor

public class DynamicClassReferenceInitializer
extends SimplifiedVisitor
implements InstructionVisitor, ConstantVisitor, AttributeVisitor

This InstructionVisitor initializes any constant Class.forName or .class references of all classes it visits. More specifically, it fills out the references of string constant pool entries that refer to a class 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 must be initialized before using this visitor.
