Interface WildcardType

All Superinterfaces:
  Type

    public interface WildcardType

extends Type

WildcardType represents a wildcard type expression, such as `?`, `? extends Number`, or `? super Integer`.

Since:
  1.5

Method Summary
`Type[]` | `getLowerBounds()` Returns an array of `Type` objects representing the lower bound(s) of this type variable.
`Type[]` | `getUpperBounds()` Returns an array of `Type` objects representing the upper bound(s) of this type variable.

Method Detail

### getUpperBounds

    Type[] getUpperBounds()

  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

### getLowerBounds

    Type[] getLowerBounds()

  Returns an array of `Type` objects representing the lower bound(s) of this type variable. Note that if no lower bound is explicitly declared, the lower bound is the type of `null`. In this case, a zero length array is returned.

  For each lower 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 lower 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
