Interface ParameterizedType
- Type
Represents a type which is parameterized over one or more other
types. For example,
List<Integer> is a parameterized
type, with
List parameterized over the type
Integer.
Instances of this classes are created as needed, during reflection.
On creating a parameterized type,
p, the
GenericTypeDeclaration corresponding to
p
is created and resolved. Each type argument of
p
is then created recursively; details of this process are availble
in the documentation of
TypeVariable. This creation
process only happens once; repetition has no effect.
Implementors of this interface must implement an appropriate
equals() method. This method should equate any
two instances of the implementing class that have the same
GenericTypeDeclaration and
Type
parameters.
Type[] | getActualTypeArguments()-
Returns an array of
Type objects, which gives
the parameters of this type.
|
Type | getOwnerType()- Returns the type of which this type is a member.
|
Type | getRawType()- Returns a version of this type without parameters, which corresponds
to the class or interface which declared the type.

getActualTypeArguments
public Type[] getActualTypeArguments()
Returns an array of
Type objects, which gives
the parameters of this type.
Note: the returned array may be empty. This
occurs if the supposed ParameterizedType is simply
a normal type wrapped inside a parameterized type.
- an array of
Types, representing the arguments
of this type.
getOwnerType
public Type getOwnerType()
Returns the type of which this type is a member. For example,
in Top<String>.Bottom<Integer>,
Bottom<Integer> is a member of
Top<String>, and so the latter is returned
by this method. Calling this method on top-level types (such as
Top<String>) returns null.
- the type which owns this type.
getRawType
public Type getRawType()
Returns a version of this type without parameters, which corresponds
to the class or interface which declared the type. For example,
the raw type corresponding to List<Double>
is List, which was declared by the List
class.
- the raw variant of this type (i.e. the type without
parameters).
