Package Summary Overview Summary

### class:TypeVariable [NONE]
public interface TypeVariable extends ReferenceType Represents a type variable. A type variable may be explicitly declared by a type parameter of a type, method, or constructor. A type variable may also be declared implicitly, as by the capture conversion of a wildcard type argument (see chapter 5 of The Java Language Specification ). See Java Language Specification : 4.4 Type Variables Since: 1.6 See Also: `TypeParameterElement` ## Method Summary Modifier and Type Method Description `Element` `asElement()` Returns the element corresponding to this type variable. `TypeMirror` `getLowerBound()` Returns the lower bound of this type variable. `TypeMirror` `getUpperBound()` Returns the upper bound of this type variable. ### Methods declared in interface javax.lang.model.type.TypeMirror `accept, equals, getAnnotation, getAnnotationMirrors, getAnnotationsByType, getKind, hashCode, toString` ## Method Details ### asElement Element asElement() Returns the element corresponding to this type variable. Returns: the element corresponding to this type variable ### getUpperBound TypeMirror getUpperBound() Returns the upper bound of this type variable. If this type variable was declared with no explicit upper bounds, the result is `java.lang.Object`. If it was declared with multiple upper bounds, the result is an intersection type ; individual bounds can be found by examining the result's bounds. Returns: the upper bound of this type variable See Java Language Specification : 4.9 Intersection Types ### getLowerBound TypeMirror getLowerBound() Returns the lower bound of this type variable. While a type parameter cannot include an explicit lower bound declaration, capture conversion can produce a type variable with a non-trivial lower bound. Type variables otherwise have a lower bound of `NullType`. Returns: the lower bound of this type variable See Java Language Specification : 18.1.3. Bounds
