Descriptor
T extends Comparable<T>
,
then the second occurence of T
is represented as a type variable reference and not
as a type variable, because it occurs in its own definition. A type variable which is fully
defined before its occurence in a recursive type parameter is still represented as a type
variable. For example, the recursive type parameter in the following class includes
one type variable reference:
abstract class Builder<T, THIS extends Builder<T, THIS>> { abstract T build(); final THIS self() { return (THIS) this; } }The identifier of the reference is
THIS
. The occurence of type variable T
in the recursive type parameter is not represented as a reference, because it does not
occur in its own definition. It is fully defined before.
The same holds for mutually recursive type parameters. If a type variable is fully defined before the type parameter in whose bound it occurs, it is represented as a type variable. It is represented as a type variable reference if it is defined after the type parameter in whose bound it occurs.
The type variable reference may be followed to obtain the original type variable.
Note that a type variable and a reference to that type variable may have different type annotations. Type annotations on the reference may be looked up from the reference, but when the reference is followed, the result is the original type variable with its own type annotations.

name
Description copied from class:Type
Returns the name of this type (or its erasure in case of generic types) as aDotName
, using theClass.getName()
format. Specifically:- for primitive types and the void pseudo-type, the corresponding Java keyword
is returned (
void
,boolean
,byte
,short
,int
,long
,float
,double
,char
); - for class types, the binary name of the class is returned;
- for array types, a string is returned that consists of one or more
[
characters corresponding to the number of dimensions of the array type, followed by the element type as a single-character code for primitive types orLbinary.name.of.TheClass;
for class types (for example,[I
forint[]
or[[Ljava.lang.String;
forString[][]
); - for parameterized types, the binary name of the generic class is returned
(for example,
java.util.List
forList<String>
); - for type variables, the name of the first bound of the type variable is returned,
or
java.lang.Object
for type variables that have no bound; - for wildcard types, the name of the upper bound is returned,
or
java.lang.Object
if the wildcard type does not have an upper bound (for example,java.lang.Number
for? extends Number
).
- for primitive types and the void pseudo-type, the corresponding Java keyword
is returned (
-
identifier
Returns the identifier of this type variable reference as it appears in Java source code.For example, the following class has a recursive type parameter
E
with one reference:abstract class MyEnum<E extends MyEnum<E>> { }
The identifier of the reference isE
.- Returns:
- the identifier of this type variable reference
-
follow
Returns the type variable referred to by this reference. -
internalClassName
DotName internalClassName() -
kind
Description copied from class:Type
Returns the kind of Type this is. -
asTypeVariableReference
Description copied from class:Type
Casts this type to aTypeVariableReference
and returns it if the kind isType.Kind.TYPE_VARIABLE_REFERENCE
. Throws an exception otherwise.- Overrides:
asTypeVariableReference

- Returns:
- a

equals
Description copied from class:Type
Compares thisType
with another type. A type is equal to another type if it is of the same kind, and all of their fields are equal. This includes annotations, which must be equal as well. -
hashCode
public int hashCode()Description copied from class:Type
Computes a hash code representing this type. -
