Detailed Description

template<typename StringType, typename TypeCodeType>
class TAO::TypeCode::Case_Enum_T< StringType, TypeCodeType >

Representation of an OMG IDL defined union case for unions with Enum discriminators.

When dynamically creating a union type with a enum discriminator, there is not way that the template parameter DiscriminatorType can be specified at runtime.

Since enums are encoded as ULongs, DiscriminatorType has been replaced with CORBA::ULong.

Member Function Documentation

template<typename StringType, typename TypeCodeType>

TAO_BEGIN_VERSIONED_NAMESPACE_DECL TAO::TypeCode::Case< StringType, TypeCodeType > * TAO::TypeCode::Case_Enum_T< StringType, TypeCodeType >::clone

(

void

)

const [inline, virtual]

Cloning/copying operation.

Implements TAO::TypeCode::Case< StringType, TypeCodeType >.

template<typename StringType, typename TypeCodeType>

CORBA::Any * TAO::TypeCode::Case_Enum_T< StringType, TypeCodeType >::label

(

void

)

const [inline, virtual]

Return the IDL union case label value embedded within a CORBA::Any.

Implements TAO::TypeCode::Case< StringType, TypeCodeType >.

template<typename StringType, typename TypeCodeType>

bool TAO::TypeCode::Case_Enum_T< StringType, TypeCodeType >::marshal_label

(

TAO_OutputCDR &

cdr

)

const [inline, virtual]

Marshal the IDL union case label value into the given output CDR stream.

Implements TAO::TypeCode::Case< StringType, TypeCodeType >.

template<typename StringType, typename TypeCodeType>

virtual bool TAO::TypeCode::Case_Enum_T< StringType, TypeCodeType >::equal_label	(	CORBA::ULong	index,
		CORBA::TypeCode_ptr	tc
	)			const [virtual]

Verify equality of member labels.

Performing member label equality comparisons in the Case subclass allows us to avoid performing interpretive extraction of the value from the Any returned from the "right hand side" operand TypeCode since the Case subclass already knows what type and value should be extracted from the Any.

Parameters:

	index	Member index of given TypeCode tc being tested.
	tc	The TypeCode whose member "@a index" label is being tested.

Implements TAO::TypeCode::Case< StringType, TypeCodeType >.
