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
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|
Returns an array of
Typeobjects 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.
Typeobjects representing the actual type arguments to this type
TypeNotPresentException- if any of the actual type arguments refers to a non-existent type declaration
MalformedParameterizedTypeException- if any of the actual type parameters refer to a parameterized type that cannot be instantiated for any reason
Typeobject representing the class or interface that declared this type.
Typeobject representing the class or interface that declared this type
Typeobject representing the type that this type is a member of. For example, if this type is
O<T>.I<S>, return a representation of
If this type is a top-level type,
null is returned.
Typeobject representing the type that this type is a member of. If this type is a top-level type,
TypeNotPresentException- if the owner type refers to a non-existent type declaration
MalformedParameterizedTypeException- if the owner type refers to a parameterized type that cannot be instantiated for any reason
