Detailed Description

Abstract base class for that represents an IDL union case/member.

This class hides the actual IDL union member label value from the TAO::TypeCode::Union class by relying on a CORBA::Any return value that corresponds to the CORBA::TypeCode::member_label() return type. It also allows the TAO::TypeCode::Union class to marshal the member label values into a CDR stream without knowledge of the underlying member label values.

Member Function Documentation

virtual Case* TAO::TypeCode::Case::clone

(

void

)

const [pure virtual]

Cloning/copying operation.

Implemented in TAO::TypeCode::Case_T, and TAO::TypeCode::Case_Enum_T.

bool TAO::TypeCode::Case::equal	(	CORBA::ULong	index,
		CORBA::TypeCode_ptr	tc
	)		const

Check for equality of the case attributes contained by this class and the corresponding member attributes at index "@a index" in the given TypeCode tc.

virtual bool TAO::TypeCode::Case::equal_label	(	CORBA::ULong	index,
		CORBA::TypeCode_ptr	tc
	)		const [protected, pure 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.

Implemented in TAO::TypeCode::Case_T, and TAO::TypeCode::Case_Enum_T.

bool TAO::TypeCode::Case::equivalent	(	CORBA::ULong	index,
		CORBA::TypeCode_ptr	tc
	)		const

Check for equivalence of the case attributes contained by this class and the corresponding member attributes at index "@a index" in the given TypeCode tc.

virtual CORBA::Any* TAO::TypeCode::Case::label

(

void

)

const [pure virtual]

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

Implemented in TAO::TypeCode::Case_T, and TAO::TypeCode::Case_Enum_T.

bool TAO::TypeCode::Case::marshal	(	TAO_OutputCDR &	cdr,
		CORBA::ULong	offset
	)		const

Marshal this IDL union member into the given output CDR stream.

virtual bool TAO::TypeCode::Case::marshal_label

(

TAO_OutputCDR &

cdr

)

const [protected, pure virtual]

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

Implemented in TAO::TypeCode::Case_T, and TAO::TypeCode::Case_Enum_T.

char const * TAO::TypeCode::Case::name

(

void

)

const

Get the name of the union case/member.

void TAO::TypeCode::Case::name

(

char const *

the_name

)

Set the name of the union case/member.

CORBA::TypeCode_ptr TAO::TypeCode::Case::type

(

void

)

const

Get the CORBA::TypeCode of the union case/member.

Note:

The reference count is not manipulated by this method, i.e., ownership is retained by this class.

void TAO::TypeCode::Case::type

(

CORBA::TypeCode_ptr

tc

)

Set the CORBA::TypeCode of the union case/member.

Note:

CORBA::TypeCode::_duplicate() is called on the TypeCode tc.

Member Data Documentation

StringType TAO::TypeCode::Case::name_ [private]

The name of the case.

TypeCodeType TAO::TypeCode::Case::type_ [private]

Pointer to the CORBA::TypeCode of the case.

A pointer to the CORBA::TypeCode_ptr rather than the CORBA::TypeCode_ptr itself is stored since that address is well-defined. We may not know the value of the CORBA::TypeCode_ptr when creating this Case statically at compile-time, hence the indirection.

Note:

This TypeCode is released upon destruction of this Case.
