getLowerBounds
Added in API level 1
abstract fun getLowerBounds(): Array<Type!>
Returns an array of Type objects representing the lower bound(s) of this type variable. 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
ParameterizedTypefor the details of the creation process for parameterized types). - Otherwise, B is resolved.
| Return | |
|---|---|
Array<Type!> |
an array of Types representing the lower bound(s) of this type variable |
| Exceptions | |
|---|---|
java.lang.TypeNotPresentException |
if any of the bounds refers to a non-existent type declaration |
java.lang.reflect.MalformedParameterizedTypeException |
if any of the bounds refer to a parameterized type that cannot be instantiated for any reason |
getUpperBounds
Added in API level 1
abstract fun getUpperBounds(): Array<Type!>
Returns an array of Type objects representing the upper bound(s) of this type variable. 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
ParameterizedTypefor the details of the creation process for parameterized types). - Otherwise, B is resolved.
| Return | |
|---|---|
Array<Type!> |
an array of Types representing the upper bound(s) of this type variable |
| Exceptions | |
|---|---|
java.lang.TypeNotPresentException |
if any of the bounds refers to a non-existent type declaration |
java.lang.reflect.MalformedParameterizedTypeException |
if any of the bounds refer to a parameterized type that cannot be instantiated for any reason |
