public interface DynUnionOperations

extends DynAnyOperations

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.

Method Summary
TCKind	discriminator_kind()     Returns the TCKind value of the discriminators TypeCode.
DynAny	get_discriminator()     Returns the current discriminator value.
boolean	has_no_active_member()     Returns true if the union has no active member, that is, the unions value consists solely of its discriminator because the discriminator has a value that is not listed as an explicit case label.
TCKind	member_kind()     Returns the TCKind value of the currently active members TypeCode.
String	member_name()     Returns the name of the currently active member.
DynAny	member()     Returns the currently active member.
void	set_discriminator(DynAny d)     Sets the discriminator of the DynUnion to the specified value.
void	set_to_default_member()     Sets the discriminator to a value that is consistent with the value of the default case of a union.
void	set_to_no_active_member()     Sets the discriminator to a value that does not correspond to any of the unions case labels.
