org.spongepowered.asm.mixin.transformer.ClassInfo

public final class ClassInfo
extends java.lang.Object

Information about a class, used as a way of keeping track of class hierarchy information needed to support more complex mixin behaviour such as detached superclass and mixin inheritance.

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	ClassInfo.FrameData Information about frames in a method
class	ClassInfo.InterfaceMethod A method resolved in an interface via a class, return the member wrapped so that the implementing class can be retrieved.
class	ClassInfo.Method A method
static class	ClassInfo.SearchType Search type for the findInHierarchy methods, replaces a boolean flag which made calling code difficult to read
static class	ClassInfo.Traversal To all intents and purposes, the "real" class hierarchy and the mixin class hierarchy exist in parallel, this means that for some hierarchy validation operations we need to walk across to the other hierarchy in order to allow meaningful validation to occur.
static class	ClassInfo.TypeLookup When using forType(org.objectweb.asm.Type, org.spongepowered.asm.mixin.transformer.ClassInfo.TypeLookup), determines whether an array type should be returned as declared (eg.
