package java.lang.reflect;

* TypeVariable is the common superinterface for type variables of kinds.
* A type variable is created the first time it is needed by a reflective
* method, as specified in this package.
If a type variable t is referenced
* by a type (i.e, class, interface or annotation type) T, and T is declared
* by the nth enclosing class of T (see JLS 8.1.2), then the creation of t
* requires the resolution (see JVMS 5) of the ith enclosing class of T,
* for i = 0 to n, inclusive. Creating a type variable must not cause the
* creation of its bounds. Repeated creation of a type variable has no effect.
* <p>Multiple objects may be instantiated at run-time to
* represent a given type variable. Even though a type variable is
* created only once, this does not imply any requirement to cache
* instances representing the type variable. However, all instances
* representing a type variable must be equal() to each other.
* As a consequence, users of type variables must not rely on the identity
* of instances of classes implementing this interface.
* @param <D> the type of generic declaration that declared the
* underlying type variable.
* @since 1.5

public interface TypeVariable<D extends GenericDeclaration> extends Type, AnnotatedElement {
* Returns an array of {@code Type} objects representing the
* upper bound(s) of this type variable.
Note that if no upper bound is
* explicitly declared, the upper bound is {@code Object}.
* <p>For each upper bound B: <ul> <li>if B is a parameterized
* type or a type variable, it is created, (see {@link
* java.lang.reflect.ParameterizedType ParameterizedType} for the
* details of the creation process for parameterized types).
* <li>Otherwise, B is resolved.
* @throws TypeNotPresentException
if any of the
*bounds refers to a non-existent type declaration
* @throws MalformedParameterizedTypeException if any of the
*bounds refer to a parameterized type that cannot be instantiated
*for any reason
* @return an array of {@code Type}s representing the upper
*bound(s) of this type variable

Type[] getBounds();

* Returns the {@code GenericDeclaration} object representing the
* generic declaration declared this type variable.
* @return the generic declaration declared for this type variable.
* @since 1.5

D getGenericDeclaration();

* Returns the name of this type variable, as it occurs in the source code.
* @return the name of this type variable, as it appears in the source code

String getName();

* Returns an array of AnnotatedType objects that represent the use of
* types to denote the upper bounds of the type parameter represented by
* this TypeVariable. The order of the objects in the array corresponds to
* the order of the bounds in the declaration of the type parameter.
* Returns an array of length 0 if the type parameter declares no bounds.
* @return an array of objects representing the upper bounds of the type variable
* @since 1.8
