TypeVariable (Java Platform SE 7 )

Type Parameters:

D - the type of generic declaration that declared the underlying type variable.

All Superinterfaces:

Type
```
public interface TypeVariable<D extends GenericDeclaration>
extends Type
```
Multiple objects may be instantiated at run-time to represent a given type variable. Even though a type variable is created only once, this does not imply any requirement to cache instances representing the type variable. However, all instances representing a type variable must be equal() to each other. As a consequence, users of type variables must not rely on the identity of instances of classes implementing this interface.

Since:

1.5

- Method Summary Methods Modifier and Type Method and Description Type[] getBounds()
  Returns an array of Type objects representing the upper bound(s) of this type variable.
  D getGenericDeclaration()
  Returns the GenericDeclaration object representing the generic declaration declared this type variable.
  String getName()
  Returns the name of this type variable, as it occurs in the source code.

- Method Detail
  - getBounds
```
Type[] getBounds()
```
    Returns an array of
    Type
    objects representing the upper bound(s) of this type variable. Note that if no upper bound is explicitly declared, the upper bound is
    Object
    .
    
    For each upper bound B:
    - if B is a parameterized type or a type variable, it is created, (see ParameterizedType for the details of the creation process for parameterized types).
    - Otherwise, B is resolved.
    Returns:
    
    an array of Types representing the upper bound(s) of this type variable
    
    Throws:
    
    TypeNotPresentException - if any of the bounds refers to a non-existent type declaration
    
    MalformedParameterizedTypeException - if any of the bounds refer to a parameterized type that cannot be instantiated for any reason
  - getGenericDeclaration
```
D getGenericDeclaration()
```
    Returns the GenericDeclaration object representing the generic declaration declared this type variable.
    
    Returns:
    
    the generic declaration declared for this type variable.

  - getName
```
String getName()
```
    Returns the name of this type variable, as it occurs in the source code.
    
    Returns:
    
    the name of this type variable, as it appears in the source code
