interface  | 
ParameterizedType
ParameterizedType represents a parameterized type such as
 Collection<String>. 
 | 
interface  | 
TypeVariable<D extends GenericDeclaration>
TypeVariable is the common superinterface for type variables of kinds.

Type object that represents the declared type for
 the field represented by this Field object. | 
Type[] | 
WildcardType.getLowerBounds()
Returns an array of  
Type objects representing the
 lower bound(s) of this type variable. | 
Type | 
ParameterizedType.getOwnerType()
Returns a  
Type object representing the type that this type
 is a member of. | 
Type | 
Parameter.getParameterizedType()
Returns a  
Type object that identifies the parameterized
 type for the parameter represented by this Parameter
 object. | 
Type |
