public interface DeclaredType
- extends
ReferenceType
Represents a declared type, either a class type or an interface type.
This includes parameterized types such as java.util.Set<String>
as well as raw types.
While a TypeDeclaration represents the declaration
of a class or interface, a DeclaredType represents a class
or interface type, the latter being a use of the former.
See
TypeDeclaration for more on this distinction.
A DeclaredType may represent a type
for which details (declaration, supertypes, etc.) are unknown.
This may be the result of a processing error, such as a missing class file,
and is indicated by
getDeclaration() returning null.
Other method invocations on such an unknown type will not, in general,
return meaningful results.

getDeclaration
TypeDeclaration getDeclaration()
- Returns the declaration of this type.
Returns null if this type's declaration is unknown. This may
be the result of a processing error, such as a missing class file.
-
-
-
Returns:
- the declaration of this type, or null if unknown
getContainingType
DeclaredType getContainingType()
- Returns the type that contains this type as a member.
Returns null if this is a top-level type.
For example, the containing type of O.I<S>
is the type O, and the containing type of
O<T>.I<S> is the type O<T>.
-
-
-
Returns:
- the type that contains this type,
or null if this is a top-level type
getActualTypeArguments
Collection<
TypeMirror> getActualTypeArguments()
- Returns (in order) the actual type arguments of this type.
For a generic type nested within another generic type
(such as
Outer<String>.Inner<Number>), only the type
arguments of the innermost type are included.
-
-
-
Returns:
- the actual type arguments of this type, or an empty collection
if there are none
getSuperinterfaces
Collection<
InterfaceType> getSuperinterfaces()
- Returns the interface types that are direct supertypes of this type.
These are the interface types implemented or extended
by this type's declaration, with any type arguments
substituted in.
For example, the interface type extended by
java.util.Set<String> is java.util.Collection<String>.
-
-
-
Returns:
- the interface types that are direct supertypes of this type,
or an empty collection if there are none
