## Class TypeSimplifier

- java.lang.Object
- - javax.lang.model.util.AbstractTypeVisitor6<R,​P>
  - - javax.lang.model.util.SimpleTypeVisitor6<javax.lang.model.type.TypeMirror,​State>
    - - com.google.web.bindery.requestfactory.apt.TypeSimplifier

- All Implemented Interfaces:
    `javax.lang.model.type.TypeVisitor<javax.lang.model.type.TypeMirror,​State>`

      public class TypeSimplifier
      extends javax.lang.model.util.SimpleTypeVisitor6<javax.lang.model.type.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>`
