Detailed Description

CORBA::TypeCode implementation for OMG IDL types with empty parameter lists.

This class implements a CORBA::TypeCode for OMG IDL types with empty parameter lists.

Note:
Empty_Param TypeCodes are not reference counted in TAO since they are static, exist as constants for the length of a given OS process, and cannot be created through the CORBA::ORB or CORBA::TypeCodeFactory interfaces.

TAO_BEGIN_VERSIONED_NAMESPACE_DECL bool TAO::TypeCode::Empty_Param::tao_marshal (  TAO_OutputCDR &  cdr,
CORBA::ULong  offset
)  const [virtual]
 

Marshal this TypeCode into a CDR output stream.

Marshal this TypeCode into the cdr output CDR stream, excluding the TypeCode kind. Existing cdr contents will not be altered. The marshaled TypeCode will be appended to the given cdr CDR output stream.

Parameters:
cdr Output CDR stream into which the TypeCode will be marshaled.
offset Number of bytes currently in the output CDR stream, including the top-level TypeCode TCKind. This argument is useful for recursive TypeCodes. TypeCodes that contain other TypeCodes should pass an updated offset value to the marshaling operation for those contained TypeCodes.
Returns:
true if marshaling was successful.
Note:
This is a TAO-specific method that is not part of the standard CORBA::TypeCode interface.

If this method returns false, the contents of the cdr output CDR stream are undefined.

Implements CORBA::TypeCode.
