Class AnnotatedTypeComparer<R>

java.lang.Object

org.checkerframework.framework.type.visitor.AnnotatedTypeScanner<R,AnnotatedTypeMirror>

org.checkerframework.framework.type.visitor.AnnotatedTypeComparer<R>

All Implemented Interfaces:

AnnotatedTypeVisitor<R,AnnotatedTypeMirror>

Direct Known Subclasses:

AnnotatedTypeMerger

public abstract class AnnotatedTypeComparer<R>
extends AnnotatedTypeScanner<R,AnnotatedTypeMirror>

A TypeVisitor that takes two AnnotatedTypeMirrors as parameters, and visits them simultaneously. Both Annotated Type Mirrors must have the same structure or else the various asserts will fail.
