Class TypeSimplifier

java.lang.Object

javax.lang.model.util.AbstractTypeVisitor6<R,P>

javax.lang.model.util.SimpleTypeVisitor6<TypeMirror,State>

com.google.web.bindery.requestfactory.apt.TypeSimplifier

All Implemented Interfaces:

TypeVisitor<TypeMirror,State>

public class TypeSimplifier
extends SimpleTypeVisitor6<TypeMirror,State>

Utility type for reducing complex type declarations to ones suitable for determining assignability based on RequestFactory's type-mapping semantics.

Rules:

• primitive type -> boxed type (optional)
• void -> Void (optional)
• <T extends Foo> -> Foo
• ? extends Foo -> Foo
• Foo<complex type> -> Foo<simplified type>
