    - #### qualifiedTypeName

          String qualifiedTypeName()

      Deprecated, for removal: This API element is subject to removal in a future version.
      Return qualified name of type excluding any dimension information.

      For example, a two dimensional array of String returns "`java.lang.String`".

      Returns:
        qualified name of this type excluding any dimension information.

    - #### simpleTypeName

          String simpleTypeName()

      Deprecated, for removal: This API element is subject to removal in a future version.
      Return the simple name of this type excluding any dimension information. This is the unqualified name of the type, except that for nested types only the identifier of the innermost type is included.

      For example, the class `Outer.Inner` returns "`Inner`".

      Returns:
        the simple name of this type excluding any dimension information.

    - #### dimension

          String dimension()

      Deprecated, for removal: This API element is subject to removal in a future version.
      Return the type's dimension information, as a string.

      For example, a two dimensional array of String returns "`[][]`".

      Returns:
        the type's dimension information as a string.

    - #### toString

          String toString()

      Deprecated, for removal: This API element is subject to removal in a future version.
      Return a string representation of the type. This includes any dimension information and type arguments.

      For example, a two dimensional array of String may return "`java.lang.String[][]`", and the parameterized type `List<Integer>` may return "`java.util.List<java.lang.Integer>`".

      Overrides:
        `toString` in class `Object`
      Returns:
        a string representation of the type.
