Member Function Documentation
| virtual void Ceylan::Visitable::accept | ( | Visitor & | visitor | ) | [pure virtual] |
Allows given visitor to visit this object, thanks to a callback: 'visitor.visit( *this ) ;'.
- Exceptions:
-
VisitException if the visit failed.
- Note:
- This method cannot be implemented here, as the visitor must declare its 'visit' method which must accept a specific datatype, not a generic one such as Visitable. Otherwise, there would be ambiguous calls.
Implemented in Ceylan::Tree< Content >, Ceylan::XML::XMLMarkup, and Ceylan::XML::XMLText.
Assignment operator made private to ensure that it will never be called.
The compiler should complain whenever this undefined operator is called, implicitly or not.
