Member Function Documentation

accept()

virtual bool Syndication::AbstractParser::accept ( const DocumentSource & source ) const

pure virtual

Lets the parser check if it can parse the passed source.

Parser implementations should do a quick check for the file format (i.e. check for feed format and version number in the root element) to find out if the source is in a supported format. They should not completely parse the document to test for full compliance to the format specification.

Parameters

source

the document source to be checked

Returns

whether source seems to be in a format supported by the parser

Implemented in Syndication::Atom::Parser, Syndication::RDF::Parser, and Syndication::RSS2::Parser.

format()

virtual QString Syndication::AbstractParser::format ( ) const

pure virtual

Returns the name of the format supported by this parser.

Returns

a string like "rss2", "atom" or "rdf"

Implemented in Syndication::Atom::Parser, Syndication::RDF::Parser, and Syndication::RSS2::Parser.

parse()

virtual SpecificDocumentPtr Syndication::AbstractParser::parse ( const DocumentSource & source ) const

pure virtual

Lets the parser parse a document source.

The parser returns a valid document instance if successful, or an invalid one if not.

SpecificDocument::isValid()

Parameters

source

The document source to be parsed

Returns

a newly created document parsed from source

Implemented in Syndication::Atom::Parser, Syndication::RDF::Parser, and Syndication::RSS2::Parser.
