    DynAnyOperations
  All Known Subinterfaces:
    DynValue, DynValueBox, DynValueBoxOperations, DynValueCommon, DynValueOperations
  All Known Implementing Classes:
    _DynValueStub

      public interface DynValueCommonOperations
      extends DynAnyOperations

  DynValueCommon provides operations supported by both the DynValue and DynValueBox interfaces.

- - ### Method Summary

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `boolean` | `is_null()` Returns true if the DynValueCommon represents a null value type.
    `void` | `set_to_null()` Changes the representation of a DynValueCommon to a null value type.
    `void` | `set_to_value()` Replaces a null value type with a newly constructed value.

- - ### Method Detail

    - #### is_null

          boolean is_null()

      Returns true if the DynValueCommon represents a null value type.

    - #### set_to_null

          void set_to_null()

      Changes the representation of a DynValueCommon to a null value type.

    - #### set_to_value

          void set_to_value()

      Replaces a null value type with a newly constructed value. Its components are initialized to default values as in DynAnyFactory.create_dyn_any_from_type_code. If the DynValueCommon represents a non-null value type, then this operation has no effect.
