7 cananian 1.1 * The <code>HTypeVariable</code> interface represents a type variable
8 cananian 1.1 * declared as a formal parameter to a generic class, interface, or
9 cananian 1.1 * method. Example: <code>A</code> in <code>Collection<A></code>.
10 cananian 1.1 * This interface embodies commonality among all type variables.
11 cananian 1.1 * Every actual type variable supports one of the two subinterfaces
12 cananian 1.1 * <code>HMethodTypeVariable</code> or <code>HClassTypeVariable</code>.
13 cananian 1.1 * <p>
14 cananian 1.1 * Note that implementations of this interface are free to return
15 cananian 1.1 * distinct objects for the same type variable; the identity of
16 cananian 1.1 * an objects implementing this interface may not be used to test for
17 cananian 1.1 * identity among the type variables they represent. (In other words,
18 cananian 1.1 * this interface does not extend <code>ReferenceUnique</code>.)
