public Interface TypeVariable

extends ReferenceType
Imports
javax.lang.model.element.Element, .TypeParameterElement
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).

Method Summary

Modifier and TypeMethod and Description
public Element

Returns:

the element corresponding to this type variable
asElement()

Returns the element corresponding to this type variable.

public TypeMirror

Returns:

the lower bound of this type variable
getLowerBound()

Returns the lower bound of this type variable.

public TypeMirror

Returns:

the upper bound of this type variable
getUpperBound()

Returns the upper bound of this type variable.

Method Detail

asElementback to summary
public Element asElement()

Returns the element corresponding to this type variable.

Returns:Element

the element corresponding to this type variable

getLowerBoundback to summary
public 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:TypeMirror

the lower bound of this type variable

Java Language Specification
18.1.3 Bounds
getUpperBoundback to summary
public 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:TypeMirror

the upper bound of this type variable
