public interface ParameterizedType
ParameterizedType represents a parameterized type such as Collection<String>.
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.
Method Summary | |
---|---|
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. |
Method Detail |
---|
Type[] getActualTypeArguments()
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.
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 reasonType getRawType()
Type getOwnerType()
O<T>.I<S>
,
return a representation of O<T>
.
If this type is a top-level type, null is returned.
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
