Creating a type variable must not cause the + * creation of its bounds. Repeated creation of a type variable has no effect. + * + *

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 the type of generic declaration that declared the + * underlying type variable. + * + * @since 1.5 + */ +public interface TypeVariable extends Type { + /** + * Returns an array of {@code Type} objects representing the + * upper bound(s) of this type variable.
