impl mozIAsyncFavicons
[src]

[src]

/**
   * Declares that a given page uses a favicon with the given URI and
   * attempts to fetch and save the icon data by loading the favicon URI
   * through an async network request.
   *
   * If the icon data already exists, we won't try to reload the icon unless
   * aForceReload is true.  Similarly, if the icon is in the failed favicon
   * cache we won't do anything unless aForceReload is true, in which case
   * we'll try to reload the favicon.
   *
   * This function will only save favicons for pages that are already stored in
   * the database, like visited pages or bookmarks.  For any other URIs, it
   * will succeed but do nothing.  This function will also ignore the error
   * page favicon URI (see FAVICON_ERRORPAGE_URL below).
   *
   * Icons that fail to load will automatically be added to the failed favicon
   * cache, and this function will not save favicons for non-bookmarked URIs
   * when history is disabled.
   *
   * @note This function is identical to
   *       nsIFaviconService::setAndLoadFaviconForPage.
   *
   * @param aPageURI
   *        URI of the page whose favicon is being set.
   * @param aFaviconURI
   *        URI of the favicon to associate with the page.
   * @param aForceReload
   *        If aForceReload is false, we try to reload the favicon only if we
   *        don't have it or it has expired from the cache.  Setting
   *        aForceReload to true causes us to reload the favicon even if we
   *        have a usable copy.
   * @param aFaviconLoadType
   *        Set to FAVICON_LOAD_PRIVATE if the favicon is loaded from a private
   *        browsing window.  Set to FAVICON_LOAD_NON_PRIVATE otherwise.
   * @param [optional] aCallback
   *        Once we're done setting and/or fetching the favicon, we invoke this
   *        callback.
   * @param [optional] aLoadingPrincipal
   *        Principal of the page whose favicon is being set. If this argument
   *        is omitted, the loadingPrincipal defaults to the nullPrincipal.
   * @param [optional] aRequestContextID
   *        used to inform Necko of how to link the
   *        favicon request with other requests in the same tab.
   *
   * @see nsIFaviconDataCallback in nsIFaviconService.idl.

/**
   * Sets the data for a given favicon URI either by replacing existing data in
   * the database or taking the place of otherwise fetched icon data when
   * calling setAndFetchFaviconForPage later.
   *
   * Favicon data for favicon URIs that are not associated with a page URI via
   * setAndFetchFaviconForPage will be stored in memory, but may be expired at
   * any time, so you should make an effort to associate favicon URIs with page
   * URIs as soon as possible.
   *
   * It's better to not use this function for chrome: icon URIs since you can
   * reference the chrome image yourself. getFaviconLinkForIcon/Page will ignore
   * any associated data if the favicon URI is "chrome:" and just return the
   * same chrome URI.
   *
   * This function does NOT send out notifications that the data has changed.
   * Pages using this favicons that are visible in history or bookmarks views
   * will keep the old icon until they have been refreshed by other means.
   *
   * This function tries to optimize the favicon size, if it is bigger
   * than a defined limit we will try to convert it to a 16x16 png image.
   * If the conversion fails and favicon is still bigger than our max accepted
   * size it won't be saved.
