Public Member Functions

virtual const String & getType () const =0

 Creates a new object.

virtual void destroyInstance (Archive *)=0
 Destroys an object which was created by this factory.

Detailed Description

Abstract factory class, archive codec plugins can register concrete subclasses of this.

Remarks:
All access to 'archives' (collections of files, compressed or just folders, maybe even remote) is managed via the abstract Archive class. Plugins are expected to provide the implementation for the actual codec itself, but because a subclass of Archive has to be created for every archive, a factory class is required to create the appropriate subclass.
So archive plugins create a subclass of Archive AND a subclass of ArchiveFactory which creates instances of the Archive subclass. See the 'Zip' and 'FileSystem' plugins for examples. Each Archive and ArchiveFactory subclass pair deal with a single archive type (identified by a string).
