  /**

  * Call this method from an after insert FeedItem trigger.

  * It updates the feed items passed in and preserves @mentions.

*/

  public static void edit(FeedItem[] feedItems) {

    String communityId = Network.getNetworkId();

    List<String> feedItemIds = new List<String>();

    for (FeedItem f : feedItems) {

        feedItemIds.add(f.id);

    }

        // Get all feed items passed into the trigger (Step #1).

    ConnectApi.BatchResult[] results = ConnectApi.ChatterFeeds.getFeedElementBatch(communityId, feedItemIds);

    for (ConnectApi.BatchResult result : results) {

        if (result.isSuccess()) {

            Object theResult = result.getResult();

            if (theResult instanceof ConnectApi.FeedItem) {

                ConnectApi.FeedItem item = (ConnectApi.FeedItem) theResult;

                // Convert message segments into input segments (Step #2a).

                ConnectApi.FeedItemInput input = ConnectApiHelper.createFeedItemInputFromBody(item.body);

                // Modify the input segments as you see fit (Step #2b).

                modifyInput(input);

                // Update the feed item (Step #2c).

                // We need to update one feed item at a time because there isn't a batch update method yet.

                ConnectApi.ChatterFeeds.updateFeedElement(communityId, item.id, input);

            }

            else {

                // Do nothing. Posting other feed element types isn't supported.

            }

        }

        else {

                System.debug('Failure in batch feed element retrieval: ' + result.getErrorMessage());

        }

    }

}
