org.glavo.classfile.impl.ClassHierarchyImpl
public final class ClassHierarchyImpl extends Object
Class hierarchy resolution framework is answering questions about classes assignability, common classes ancestor and whether the class represents an interface. All the requests are handled without class loading nor full verification, optionally with incomplete dependencies and with focus on maximum performance.
