org.omg.CORBA
Interface DynUnion

All Superinterfaces:

DynAny, Object

---

public interface DynUnion

extends Object, DynAny

The DynUnion interface represents a DynAny object that is associated with an IDL union. Union values can be traversed using the operations defined in DynAny. The first component in the union corresponds to the discriminator; the second corresponds to the actual value of the union. Calling the method next() twice allows you to access both components.

---

Method Summary
TCKind	discriminator_kind()           Returns the TCKind object associated with the discriminator of this union.
DynAny	discriminator()           Returns a DynAny object reference that must be narrowed to the type of the discriminator in order to insert/get the discriminator value.
TCKind	member_kind()           Returns the TCKind associated with the member of this union.
String	member_name()           Allows for the inspection of the name of this union member without checking the value of the discriminator.
void	member_name(String arg)           Allows for the assignment of the name of this union member.
DynAny	member()           Returns a DynAny object reference that is used in order to insert/get a member of this union.
boolean	set_as_default()           Determines whether the discriminator associated with this union has been assigned a valid default value.
void	set_as_default(boolean arg)           Determines whether the discriminator associated with this union gets assigned a valid default value.

Method Detail

set_as_default

public boolean set_as_default()

Determines whether the discriminator associated with this union has been assigned a valid default value.

Returns:

true if the discriminator has a default value; false otherwise

---

set_as_default

public void set_as_default(boolean arg)

Determines whether the discriminator associated with this union gets assigned a valid default value.

Parameters:

arg - true if the discriminator gets assigned a default value

---

discriminator

public DynAny discriminator()

Returns a DynAny object reference that must be narrowed to the type of the discriminator in order to insert/get the discriminator value.

Returns:

a DynAny object reference representing the discriminator value

---

discriminator_kind

public TCKind discriminator_kind()

Returns the TCKind object associated with the discriminator of this union.

Returns:

the TCKind object associated with the discriminator of this union

---

member

public DynAny member()

Returns a DynAny object reference that is used in order to insert/get a member of this union.

Returns:

the DynAny object representing a member of this union

---

member_name

public String member_name()

Allows for the inspection of the name of this union member without checking the value of the discriminator.

Returns:

the name of this union member

---

member_name

public void member_name(String arg)

Allows for the assignment of the name of this union member.

Parameters:

arg - the new name of this union member

---

member_kind

public TCKind member_kind()

Returns the TCKind associated with the member of this union.

Returns:

the TCKind object associated with the member of this union
