public interface ParameterizedType extends Type
A parameterized type is created the first time it is needed by a
reflective method, as specified in this package. When a
parameterized type p is created, the generic type declaration that
p instantiates is resolved, and all type arguments of p are created
recursively. See TypeVariable
for details on the creation process for type
variables. Repeated creation of a parameterized type has no effect.
Instances of classes that implement this interface must implement an equals() method that equates any two instances that share the same generic type declaration and have equal type parameters.
Modifier and Type | Method and Description |

Type[] |
getActualTypeArguments()
Returns an array of
Type objects representing the actual type
arguments to this type. |
Type |
getOwnerType()
Returns a
Type object representing the type that this type
is a member of. |
Type |
getRawType()
Returns the
Type object representing the class or interface
that declared this type. |
getTypeName
Type[] getActualTypeArguments()
Type
objects representing the actual type
arguments to this type.
Note that in some cases, the returned array be empty. This can occur if this type represents a non-parameterized type nested within a parameterized type.

Type
object representing the type that this type
is a member of. For example, if this type is O<T>.I<S>
,
return a representation of O<T>
.
If this type is a top-level type, null
is returned.
