Interface ParameterizedType

All Superinterfaces:

Type

public interface ParameterizedType
extends Type

Represents an invocation of a generic class or interface. For example, given the generic interface List<E>, possible invocations include:

       List<String>
       List<T extends Number>
       List<?>
 

A generic inner class Outer<T>.Inner<S> might be invoked as:

       Outer<Number>.Inner<String>
 

Since:

1.5

Method Summary

Method Detail

asClassDoc

ClassDoc asClassDoc()

Return the generic class or interface that declared this type.

Specified by:

asClassDoc in interface Type

Returns:

the generic class or interface that declared this type.

typeArguments

Type[] typeArguments()

Return the actual type arguments of this type. For a generic type that is nested within some other generic type (such as Outer<T>.Inner<S>), only the type arguments of the innermost type are included.

Returns:

the actual type arguments of this type.

superclassType

Type superclassType()

Return the class type that is a direct supertype of this one. This is the superclass of this type's declaring class, with type arguments substituted in. Return null if this is an interface type.

For example, if this parameterized type is java.util.ArrayList<String>, the result will be java.util.AbstractList<String>.

Returns:

the class type that is a direct supertype of this one.

interfaceTypes

Type[] interfaceTypes()

Return the interface types directly implemented by or extended by this parameterized type. These are the interfaces directly implemented or extended by this type's declaring class or interface, with type arguments substituted in. Return an empty array if there are no interfaces.

For example, the interface extended by java.util.Set<String> is java.util.Collection<String>.

Returns:

the interface types directly implemented by or extended by this parameterized type.

containingType

Type containingType()

Return the type that contains this type as a member. Return null is this is a top-level type.

For example, the containing type of AnInterface.Nested<Number> is the ClassDoc representing AnInterface, and the containing type of Outer<String>.Inner<Number> is the ParameterizedType representing Outer<String>.

Returns:

the type that contains this type as a member.
