Interface WildcardType

All Superinterfaces:: AnnotatedConstruct, TypeMirror

public interface WildcardType extends TypeMirror

Represents a wildcard type argument. Examples include:

  ?
  ? extends Number
  ? super T

A wildcard may have its upper bound explicitly set by an extends clause, its lower bound explicitly set by a super clause, or neither (but not both).

See Java Language Specification:: 4.5.1 Type Arguments of Parameterized Types
Since:: 1.6

Modifier and Type	Method	Description
`<R,P> R`	`accept(TypeVisitor<R,P> v, P p)`	Applies a visitor to this type.
`boolean`	`equals(Object obj)`	Obeys the general contract of `Object.equals`.
`<A extends Annotation> A`	`getAnnotation(Class<A> annotationType)`	Returns this construct's annotation of the specified type if such an annotation is present, else `null`.
`List<? extends AnnotationMirror>`	`getAnnotationMirrors()`	Returns the annotations that are directly present on this construct.
`<A extends Annotation> A[]`	`getAnnotationsByType(Class<A> annotationType)`	Returns annotations of the specified type that are associated with this construct.
`TypeKind`	`getKind()`	Returns the `kind` of this type.
`int`	`hashCode()`	Obeys the general contract of `Object.hashCode`.
`String`	`toString()`	Returns an informative string representation of this type.
