/**
|
|
* This module provides an asynchronous API for managing bookmarks.
|
|
*
|
|
* Bookmarks are organized in a tree structure, and include URLs, folders and
|
|
* separators. Multiple bookmarks for the same URL are allowed.
|
|
*
|
|
* Note that if you are handling bookmarks operations in the UI, you should
|
|
* not use this API directly, but rather use PlacesTransactions.jsm, so that
|
|
* any operation is undo/redo-able.
|
|
*
|
|
* Each bookmark-item is represented by an object having the following
|
|
* properties:
|
|
*
|
|
* - guid (string)
|
|
* The globally unique identifier of the item.
|
|
* - parentGuid (string)
|
|
* The globally unique identifier of the folder containing the item.
|
|
* This will be an empty string for the Places root folder.
|
|
* - index (number)
|
|
* The 0-based position of the item in the parent folder.
|
|
* - dateAdded (Date)
|
|
* The time at which the item was added.
|
|
* - lastModified (Date)
|
|
* The time at which the item was last modified.
|
|
* - type (number)
|
|
* The item's type, either TYPE_BOOKMARK, TYPE_FOLDER or TYPE_SEPARATOR.
|
|
*
|
|
* The following properties are only valid for URLs or folders.
|
|
*
|
|
* - title (string)
|
|
* The item's title, if any. Empty titles and null titles are considered
|
|
* the same, and the property is unset on retrieval in such a case.
|
|
* Titles longer than DB_TITLE_LENGTH_MAX will be truncated.
|
|
*
|
|
* The following properties are only valid for URLs:
|
|
*
|
|
* - url (URL, href or nsIURI)
|
|
* The item's URL. Note that while input objects can contains either
|
|
* an URL object, an href string, or an nsIURI, output objects will always
|
|
* contain an URL object.
|
|
* An URL cannot be longer than DB_URL_LENGTH_MAX, methods will throw if a
|
|
* longer value is provided.
|
|
*
|
|
* Each successful operation notifies through the nsINavBookmarksObserver
|
|
* interface. To listen to such notifications you must register using
|
|
* nsINavBookmarksService addObserver and removeObserver methods.
|
|
* Note that bookmark addition or order changes won't notify onItemMoved for
|
|
* items that have their indexes changed.
|
|
* Similarly, lastModified changes not done explicitly (like changing another
|
|
* property) won't fire an onItemChanged notification for the lastModified
|
|
* property.
|
|
* @see nsINavBookmarkObserver

|
|
* the number of items, including the root item itself, which are

|

* WARNING: since the function may be called for each item, using

* this option can slow down the process significantly if the

* highly recommended to avoid any synchronous I/O or DB queries.
