## Interface WildcardType

- All Superinterfaces:
    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).

  Since:
