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
