Class ClassFileHierarchyInitializer

java.lang.Object
  proguard.classfile.util.ClassFileHierarchyInitializer

All Implemented Interfaces:

ClassFileVisitor, CpInfoVisitor

public class ClassFileHierarchyInitializer

extends Object

implements ClassFileVisitor, CpInfoVisitor

This ClassFileVisitor initializes the class hierarchy of all class files that it visits.

Visited class files are added to the subclass list of their superclasses and interfaces. These subclass lists make it more convenient to travel down the class hierarchy.

Visited library class files get direct references to their superclasses and interfaces, replacing the superclass names and interface names. The direct references are equivalent to the names, but they are more efficient to work with.

This visitor optionally prints warnings if some items can't be found.

Constructor Summary

ClassFileHierarchyInitializer(ClassPool programClassPool, ClassPool libraryClassPool)
Creates a new ClassFileReferenceInitializer that initializes the hierarchy of all visited class files, printing warnings if some classes can't be found.

ClassFileHierarchyInitializer(ClassPool programClassPool, ClassPool libraryClassPool, boolean warn)
Creates a new ClassFileReferenceInitializer that initializes the hierarchy of all visited class files, optionally printing warnings if some classes can't be found.

Method Summary

int	getWarningCount() Returns the number of warnings printed about unresolved references to superclasses or interfaces.
