* HOW QUERY UPDATING WORKS
|
|
*
|
|
* Queries are different than bookmark folders in that we can not always do
|
|
* dynamic updates (easily) and updates are more expensive. Therefore, we do
|
|
* NOT query if we are not open and want to see if we have any children (for
|
|
* drawing a twisty) and always assume we will.
|
|
*
|
|
* When the container is opened, we execute the query and register the
|
|
* listeners. Like bookmark folders, we stay registered even when closed, and
|
|
* clear ourselves as soon as a message comes in. This lets us respond quickly
|
|
* if the user closes and reopens the container.
|
|
*
|
|
* We try to handle the most common notifications for the most common query
|
|
* types dynamically, that is, figuring out what should happen in response to
|
|
* a message without doing a requery. For complex changes or complex queries,
|
|
* we give up and requery.

/**

|
* HOW DYNAMIC FOLDER UPDATING WORKS
|
|
*
|
|
* When you create a result, it will automatically keep itself in sync with
|
|
* stuff that happens in the system. For folder nodes, this means changes to
|
|
* bookmarks.
|
|
*
|
|
* A folder will fill its children "when necessary." This means it is being
|
|
* opened or whether we need to see if it is empty for twisty drawing. It will
|
|
* then register its ID with the main result object that owns it. This result
|
|
* object will listen for all bookmark notifications and pass those
|
|
* notifications to folder nodes that have registered for that specific folder
|
|
* ID.
|
|
*
|
|
* When a bookmark folder is closed, it will not clear its children. Instead,
|
|
* it will keep them and also stay registered as a listener. This means that
|
|
* you can more quickly re-open the same folder without doing any work. This
|
|
* happens a lot for menus, and bookmarks don't change very often.
|
|
*
|
|
* When a message comes in and the folder is open, we will do the correct
|
|
* operations to keep ourselves in sync with the bookmark service. If the
|
|
* folder is closed, we just clear our list to mark it as invalid and
|
|
* unregister as a listener. This means we do not have to keep maintaining
|
|
* an up-to-date list for the entire bookmark menu structure in every place
|
|
* it is used.
