/**
 
* 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
