Detailed Description

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

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.

template<typename StringType , typename TypeCodeType>
TAO::TypeCode::Case< StringType, TypeCodeType >::Case ( void  )

Member Function Documentation

template<typename StringType, typename TypeCodeType>
virtual Case* TAO::TypeCode::Case< StringType, TypeCodeType >::clone ( void  ) const [pure virtual]
template<typename StringType , typename TypeCodeType >
bool TAO::TypeCode::Case< StringType, TypeCodeType >::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.

template<typename StringType, typename TypeCodeType>
virtual bool TAO::TypeCode::Case< StringType, TypeCodeType >::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:
indexMember index of given TypeCode tc being tested.
tcThe TypeCode whose member "@a index" label is being tested.

Implemented in TAO::TypeCode::Case_T< DiscriminatorType, StringType, TypeCodeType >, and TAO::TypeCode::Case_Enum_T< StringType, TypeCodeType >.

template<typename StringType , typename TypeCodeType >
bool TAO::TypeCode::Case< StringType, TypeCodeType >::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.

template<typename StringType, typename TypeCodeType>
virtual CORBA::Any* TAO::TypeCode::Case< StringType, TypeCodeType >::label ( void  ) const [pure virtual]
template<typename StringType , typename TypeCodeType >
bool TAO::TypeCode::Case< StringType, TypeCodeType >::marshal ( TAO_OutputCDR cdr,
CORBA::ULong  offset 
) const

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

template<typename StringType, typename TypeCodeType>
virtual bool TAO::TypeCode::Case< StringType, TypeCodeType >::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< DiscriminatorType, StringType, TypeCodeType >, and TAO::TypeCode::Case_Enum_T< StringType, TypeCodeType >.

template<typename StringType , typename TypeCodeType >
char const * TAO::TypeCode::Case< StringType, TypeCodeType >::name ( void  ) const

Get the name of the union case/member.

template<typename StringType , typename TypeCodeType >
void TAO::TypeCode::Case< StringType, TypeCodeType >::name ( char const *  the_name)

Set the name of the union case/member.

template<typename StringType , typename TypeCodeType >
CORBA::TypeCode_ptr TAO::TypeCode::Case< StringType, TypeCodeType >::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.
template<typename StringType , typename TypeCodeType >
void TAO::TypeCode::Case< StringType, TypeCodeType >::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

template<typename StringType, typename TypeCodeType>
StringType TAO::TypeCode::Case< StringType, TypeCodeType >::name_ [private]

The name of the case.

template<typename StringType, typename TypeCodeType>
TypeCodeType TAO::TypeCode::Case< StringType, TypeCodeType >::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.
