Akregator::Backend::Storage Class Reference
#include <storage.h>
Inheritance diagram for Akregator::Backend::Storage:

Detailed Description
Storage is the main interface to the article archive.It creates and manages FeedStorage objects handling the article list for a feed.
An archive implementation must implement Storage, FeedStorage and StorageFactory. See mk4storage for an example.

Member Function Documentation
virtual void Akregator::Backend::Storage::initialize | ( | const QStringList & | params | ) | [pure virtual] |
initializes the storage object with given parameters
Implemented in Akregator::Backend::StorageDummyImpl.
virtual bool Akregator::Backend::Storage::open | ( | bool | autoCommit = false |
) | [pure virtual] |
Open storage and prepare it for work.
- Returns:
- true on success.
Implemented in Akregator::Backend::StorageDummyImpl.
virtual bool Akregator::Backend::Storage::commit | ( | ) | [pure virtual] |
Commit changes made in feeds and articles, making them persistent.
- Returns:
- true on success.
Implemented in Akregator::Backend::StorageDummyImpl.
virtual bool Akregator::Backend::Storage::rollback | ( | ) | [pure virtual] |
Rollback changes made in feeds and articles, reverting to last committed values.
- Returns:
- true on success.
Implemented in Akregator::Backend::StorageDummyImpl.
virtual bool Akregator::Backend::Storage::close | ( | ) | [pure virtual] |
Closes storage, freeing all allocated resources.
Called from destructor, so you don't need to call it directly.
- Returns:
- true on success.
Implemented in Akregator::Backend::StorageDummyImpl.
virtual FeedStorage* Akregator::Backend::Storage::archiveFor | ( | const QString & | url | ) | [pure virtual] |
virtual void Akregator::Backend::Storage::storeFeedList | ( | const QString & | opmlStr | ) | [pure virtual] |
stores the feed list in the storage backend.
This is a fallback for the case that the feeds.opml file gets corrupted
- Parameters:
-
opmlStr the feed list in OPML format
Implemented in Akregator::Backend::StorageDummyImpl.
virtual QStringList Akregator::Backend::Storage::feeds | ( | ) | const [pure virtual] |
returns a list of all feeds (URLs) stored in this archive
Implemented in Akregator::Backend::StorageDummyImpl.
virtual void Akregator::Backend::Storage::add | ( | Storage * | source | ) | [pure virtual] |
adds all feed storages from a source to this storage existing articles are replaced
Implemented in Akregator::Backend::StorageDummyImpl.
virtual void Akregator::Backend::Storage::clear | ( | ) | [pure virtual] |
