## Detailed Description

Objects of this class represent a RSS/ATOM feed, which is basically just a source for new articles. When creating a RSSFeed object, you'll just have to provide it with the URL, where the feed can be downloaded from.

This is the generic way to read feeds:

- Create a URL object with the location of the feed.
  `NSURL* url = [NSURL URLWithString:@"http://www.example.com/feed.xml"];`
- Create a RSSFeed object with the URL:
  `RSSFeed* feed = [RSSFeed initWithURL: url];`
- Fetch the contents of the feed:
  `enum RSSFeedError err = [feed fetch];`
- Optionally tell the RSSFeed to keep old articles.
  `[feed setAutoClear: NO];`
- Iterate over the articles contained in the feed. This is analogous to the iteration over a NSArray.

            int i;
            for (i=0; i<[feed count]; i++)
              {
                RSSArticle* myArticle = [feed articleAtIndex: i];
                // [...] more code here
              }

- (Class) articleClass |  |  |  |

Returns the class of the article objects. This will be a subtype of RSSArticle.

Returns:
  the article class

- (NSEnumerator*) articleEnumerator |  |  |  |

Returns:
  an enumerator for the articles in this feed

- (BOOL) autoClear |  |  |  |

Returns:
  YES, if the automatic clearing of the article list is enabled for this feed. NO otherwise.

- (void) clearArticles |  |  |  |

- (id) initWithURL: |  | (NSURL *) | aURL |  |

Designated initializer.

Parameters:

  | aURL | The URL where the feed can be downloaded from.

- (NSDate*) lastRetrieval |  |  |  |

Returns the date of last retrieval of this feed. If the feed hasn't been retrieved yet, this method returns nil.

Returns:
  The date of last retrieval as a NSDate pointer.

- (void) removeArticle: |  | (RSSArticle *) | article |  |

Deletes an article from the feed.

Parameters:

  | article | The index of the article to delete.

- (void) setArticleClass: |  | (Class) | aClass |  |

Sets the class of the article objects. This needs to be a subtype of RSSArticle.

Parameters:

  | aClass | The class newly created article objects should have.

- (void) setAutoClear: |  | (BOOL) | autoClear |  |

Lets you decide if the feed should be cleared before new articles are downloaded.

Parameters:

  | autoClear | YES, if the feed should clear its article list before fetching new articles. NO otherwise
