Please see below the description of additional requirements for the file system storage implementation.

interface ::com::sun::star::lang::XComponent

A file system storage is created either by StorageFactory or by XStorage interface and is controlled by refcounting. In case refcounting is decreased to zero the storage will be disposed automatically.

In case a storage object is disposed the elements ( substorages and substreams ) are not affected.

interface XStorage

XStorage::openStorageElement

This method returns FileSystemStorage service implementation.

XStorage::copyLastCommitTo

Since this service implementation supports no transaction this method just creates a copy of the storage in it's current state.

XStorage::copyStorageElementLastCommitTo

Since this service implementation supports no transaction this method just creates a copy of the storage in it's current state.

XStorage::removeStorageElement

If the element is opened and it is a stream element the removing will fail. If the element is opened and it is a storage element, all the contents that can be removed will be removed.

property URL

This property is not optional for this service.
