```
public class TypeReference
extends Object
```
A reference to a type appearing in a class, field or method declaration, or on an instruction. Such a reference designates the part of the class where the referenced type is appearing (e.g. an 'extends', 'implements' or 'throws' clause, a 'new' instruction, a 'catch' clause, a type cast, a local variable declaration, etc).
