    • name

      public DotName name()
      Description copied from class: Type
      Returns the raw name of this type. Primitives and void are returned as the Java keyword (void, boolean, byte, short, int, long, float, double, char). Arrays are returned using the Java reflection array syntax (e.g. [[[Ljava.lang.String;) Classes are returned as a normal DotName.

      Generic values are returned as the underlying raw value. For example, a wildcard such as ? extends Number has a raw type of Number.

      Overrides:
      name in class Type
      Returns:
      the name of this type

    • extendsBound

      public Type extendsBound()
      Returns the upper bound of this wildcard (e.g. SomeType for ? extends SomeType).

      Returns java.lang.Object if this wildcard declares a lower bound (? super SomeType).

      Returns:
      the upper bound, or Object if this wildcard has a lower bound

    • superBound

      public Type superBound()
      Returns the lower bound of this wildcard (e.g. SomeType for ? super SomeType).

      Returns null if this wildcard declares an upper bound (? extends SomeType).

      Returns:
      the lower bound, or null if this wildcard has an uper bound

    • kind

      public Type.Kind kind()
      Description copied from class: Type
      Returns the kind of Type this is.
      Specified by:
      kind in class Type
      Returns:
      the kind

    • asWildcardType

      public WildcardType asWildcardType()
      Description copied from class: Type

      Description copied from class: Type

      Overrides:
      equals in class Type
      Parameters:
      o - the type to compare to
      Returns:
