| Class<T> |
Instances of the class Class represent classes and
interfaces in a running Java application.
|
| GenericArrayType |
GenericArrayType represents an array type whose component
type is either a parameterized type or a type variable.
|
| ParameterizedType |
ParameterizedType represents a parameterized type such as
Collection<String>.
|
| TypeVariable<D extends GenericDeclaration> |
TypeVariable is the common superinterface for type variables of kinds.
|
| WildcardType |
WildcardType represents a wildcard type expression, such as
?, ? extends Number, or ? super Integer.
|
|
Type is the common superinterface for all types in the Java
programming language. These include raw types, parameterized types,
array types, type variables and primitive types.
