/**
|
|
* The Remote Container interface provides a base class for services that want
|
|
* to provide containers for bookmarks. Some examples of possible services are
|
|
* the livemarks service and the filesystem.
|
|
*
|
|
* There are two primary modes of operation: container services might create
|
|
* actual bookmarks, or they might fill containers on the fly as needed. The
|
|
* livemarks service, for example, queries the feed from time to time and
|
|
* creates actual bookmarks in the folder corresponding to the feed. This way
|
|
* the items are persistent even if the user is offline, and can be searched.
|
|
* In this mode, the service just looks for moves and deletes to update the
|
|
* corresponding bookkeeping information. It can use the normal population
|
|
* method provided by the bookmark service and need not do any work for the
|
|
* onContainerOpen message.
|
|
*
|
|
* Such a bookmark-based container service might listen for onContainerOpening
|
|
* notifications messages to see whether
|
|
|
|
*
|
|
* Persistent bookmarks are not appropriate for more short-lived data, such as
|
|
* the filesystem interface. In this case, the service can fill result nodes
|
|
* directly into the container when it is being opened. It can use the property
|
|
* bag on every result node to store data associated with each item, such as
|
|
* full path on disk. It would create additional containers for each folder,
|
|
* resgistered to its service. These dynamic containers are not bookmark
|
|
* folders in contrast to the initial item.
