Method Detail

### discriminator_type

    public TypeCode discriminator_type()

  The discriminator_type attribute describe the union’s discriminator type.

### discriminator_type_def

    public IDLType discriminator_type_def()

  The discriminator_type_def attribute identify the union’s discriminator type.

### discriminator_type_def

    public void discriminator_type_def(IDLType value)

  The discriminator_type_def attribute identify the union’s discriminator type.

### members

    public UnionMember[] members()

  The members attribute contains a description of each union member. The label of each UnionMemberDescription is a distinct value of the discriminator_type. Adjacent members can have the same name. Members with the same name must also have the same type. A label with type octet and value 0 indicates the default union member.

### members

    public void members(UnionMember[] value)

  The members attribute contains a description of each union member. The label of each UnionMemberDescription is a distinct value of the discriminator_type. Adjacent members can have the same name. Members with the same name must also have the same type. A label with type octet and value 0 indicates the default union member.
