Document Collection Factory

The factory classes have the duty to create the document collection manager.

• DocumentCollectionManagerFactory
• DocumentCollectionManagerAsyncFactory

The DocumentCollectionManagerAsyncFactory and DocumentCollectionManagerFactory creates the manager synchronously and asynchronously respectively.

DocumentCollectionManagerFactory factory = //instance
DocumentCollectionManagerAsyncFactory asyncFactory = //instance
DocumentCollectionManager manager = factory.get("database");
DocumentCollectionManagerAsync managerAsync = asyncFactory.getAsync("database");

The factories were separated intentionally, as not all databases support synchronous and asynchronous operations.
