troll.storage 0.4

Troll abstract storage layer

The troll.storage package provides an abstract approach for the storage problematics. It defines a simple, yet exhaustive, api to deal with all kind of storage.

It provides :

• A clear API as interfaces

• A base class adapter that provides a basic implementation.

• A demonstrative, yet functional, annotation descriptor, to handle annotation storages.

How does it work?

The system uses the basic zope3 components system to be flexible and pluggable. There are 3 main parts :

• the Handler : the straightforward API to store, retrieve and delete. It’s implemented as an adapter.

• the Storage : a storage object that implements IStorage. It can be a zope container or a layer to write in a relational database.

• the Stored Item : a very lightly contrained object that is to be stored in Storage.

Nothing is like code reading to understand how to use it and why to use it. I recommand you read the tests. They demonstrate all the basic usecases.
