org.omg.DynamicAny
Class DynUnionHelper

java.lang.Object
  org.omg.DynamicAny.DynUnionHelper

public abstract class DynUnionHelper
extends Object

DynUnion objects support the manipulation of IDL unions. A union can have only two valid current positions:

• zero, which denotes the discriminator
• one, which denotes the active member

The component_count value for a union depends on the current discriminator: it is 2 for a union whose discriminator indicates a named member, and 1 otherwise.
