* Represents a declared type, either a class type or an interface type.

* <i>element</i>, a {@code DeclaredType} represents a class
* or interface <i>type</i>, the latter being a use
* (or <i>invocation</i>) of the former.
* See {@link TypeElement} for more on this distinction.
*
* <p> The supertypes (both class and interface types) of a declared
* type may be found using the {@link
* Types#directSupertypes(TypeMirror)} method. This returns the
* supertypes with any type arguments substituted in.
*
* <p> This interface is also used to represent intersection types.
* An intersection type is implicit in a program rather than being
* explictly declared. For example, the bound of the type parameter
* {@code <T extends Number & Runnable>}
* is an intersection type. It is represented by a {@code DeclaredType}
* with {@code Number} as its superclass and {@code Runnable} as its
* lone superinterface.
