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.
