Detailed Description
Document interface for format-specific feed documents as parsed from a document source (see DocumentSource).
The Document classes from the several syndication formats must implement this interface. It's main purpose is to provide access for document visitors (see DocumentVisitor). Usually it is not necessary to access the format-specific document at all, use Feed for a format-agnostic interface to all feed documents supported by the library.

Member Function Documentation
| virtual bool Syndication::SpecificDocument::accept | ( | DocumentVisitor * | visitor | ) | [pure virtual] |
This must be implemented for the double dispatch technique (Visitor pattern).
The usual implementation is
return visitor->visit(this);
See also DocumentVisitor.
- Parameters:
-
visitor the visitor "visiting" this object
| virtual QString Syndication::SpecificDocument::debugInfo | ( | ) | const [pure virtual] |
Returns a description of the document for debugging purposes.
- Returns:
- debug string
| virtual bool Syndication::SpecificDocument::isValid | ( | ) | const [pure virtual] |
Returns whether this document is valid or not.
Invalid documents do not contain any useful information.
