Detailed Description
This class represents a feed document ("Channel" in RSS, "Feed" in Atom).
It contains a ordered list of items (e.g., articles) and a description of the feed (title, homepage, etc.). This interface abstracts from format-specific details of e.g. Atom::FeedDocument or RSS::Document and provides a format-agnostic, unified view on the document. This way applications using the syndication library have no need to care about the syndication format jungle at all. If necessary, format details and specialities can be accessed using the specificDocument() method.
Constructor & Destructor Documentation
◆ ~Feed()
Member Function Documentation
◆ additionalProperties()
|
pure virtual |
returns a list of feed metadata not covered by this class.
Can be used e.g. to access format extensions.
The returned map contains key value pairs, where the key is the tag name of the element, namespace prefix are resolved to the corresponding URIs. The value is the XML element as read from the document.
For example, to access the <itunes:subtitle> element, use additionalProperties()["http://www.itunes.com/dtds/podcast-1.0.dtdsubtitle"].
Currently this is only supported for RSS 0.91..0.94/2.0 and Atom formats, but not for RDF (RSS 0.9 and 1.0).
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ authors()
|
pure virtual |
returns a list of persons who created the feed content.
If there is a distinction between authors and contributors (Atom), both are added to the list, where authors are added first.
- Returns
- list of authors (and possibly other contributing persons)
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ categories()
|
pure virtual |
returns a list of categories this feed is associated with.
See Category for more information.
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ copyright()
|
pure virtual |
returns copyright information about the feed
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ debugInfo()
|
virtual |
◆ description()
|
pure virtual |
A description of the feed.
This string may contain HTML markup.(Importantly, occurrences of the characters <,'
', '&', '\'' and '"' are escaped).
- Returns
- the description as HTML, or a null string if none is specified
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ icon()
|
pure virtual |
returns an icon associated with this item.
- Returns
- an icon object, or a null icon (Not a null pointer! I.e., icon()->isNull() is
true) if no image is specified in the feed
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ image()
|
pure virtual |
returns an image associated with this item.
- Returns
- an image object, or a null image (Not a null pointer! I.e., image()->isNull() is
true) if no image is specified in the feed
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ items()
|
pure virtual |
A list of items, in the order they were parsed from the feed source.
(usually reverse chronological order, see also Item::datePublished() for sorting purposes).
- Returns
- list of items
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ language()
|
pure virtual |
The language used in the feed.
This is a global setting, which can be overridden by the contained items.
TODO: describe concrete format (language codes)
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ link()
|
pure virtual |
returns a link pointing to a website associated with this channel.
(blog, news site etc.)
- Returns
- a WWW link, or a null string if none is specified
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ specificDocument()
|
pure virtual |
returns the format-specific document this abstraction wraps.
If you want to access format-specific properties, this can be used, in combination with a DocumentVisitor.
- Returns
- a shared pointer to the wrapped document.
Implemented in Syndication::FeedAtomImpl, Syndication::FeedRDFImpl, and Syndication::FeedRSS2Impl.
◆ title()
|
pure virtual |
The title of the feed.
This string may contain HTML markup.(Importantly, occurrences of the characters <,'
', '&', '\'' and '"' are escaped).
- Returns
- the title, or a null string if none is specified
