/**
|
|
* Asynchronous API for managing history.
|
|
*
|
|
*
|
|
* The API makes use of `PageInfo` and `VisitInfo` objects, defined as follows.
|
|
*
|
|
* A `PageInfo` object is any object that contains A SUBSET of the
|
|
* following properties:
|
|
* - guid: (string)
|
|
* The globally unique id of the page.
|
|
* - url: (URL)
|
|
* or (nsIURI)
|
|
* or (string)
|
|
* The full URI of the page. Note that `PageInfo` values passed as
|
|
* argument may hold `nsIURI` or `string` values for property `url`,
|
|
* but `PageInfo` objects returned by this module always hold `URL`
|
|
* values.
|
|
* - title: (string)
|
|
* The title associated with the page, if any.
|
|
* - description: (string)
|
|
* The description of the page, if any.
|
|
* - previewImageURL: (URL)
|
|
* or (nsIURI)
|
|
* or (string)
|
|
* The preview image URL of the page, if any.
|
|
* - frecency: (number)
|
|
* The frecency of the page, if any.
|
|
* See https://developer.mozilla.org/en-US/docs/Mozilla/Tech/Places/Frecency_algorithm
|
|
* Note that this property may not be used to change the actualy frecency
|
|
* score of a page, only to retrieve it. In other words, any `frecency` field
|
|
* passed as argument to a function of this API will be ignored.
|
|
* - visits: (Array<VisitInfo>)
|
|
* All the visits for this page, if any.
|
|
*
|
|
* See the documentation of individual methods to find out which properties
|
|
* are required for `PageInfo` arguments or returned for `PageInfo` results.
|
|
*
|
|
* A `VisitInfo` object is any object that contains A SUBSET of the following
|
|
* properties:
|
|
* - date: (Date)
|
|
* The time the visit occurred.
|
|
* - transition: (number)
|
|
* How the user reached the page. See constants `TRANSITIONS.*`
|
|
* for the possible transition types.
|
|
* - referrer: (URL)
|
|
* or (nsIURI)
|
|
* or (string)
|
|
* The referring URI of this visit. Note that `VisitInfo` passed
|
|
* as argument may hold `nsIURI` or `string` values for property `referrer`,
|
|
* but `VisitInfo` objects returned by this module always hold `URL`
|
|
* values.
|
|
* See the documentation of individual methods to find out which properties
|
|
* are required for `VisitInfo` arguments or returned for `VisitInfo` results.
|
|
*
|
|
*
|
|
*
|
|
* Each successful operation notifies through the nsINavHistoryObserver
|
|
* interface. To listen to such notifications you must register using
|
|
* nsINavHistoryService `addObserver` and `removeObserver` methods.
|
|
* @see nsINavHistoryObserver
