Filtering content of the current user's friends
The method also returns a collection of status updates based on the matching tag, placing no limit on the number
of status updates to be returned. In addition, it marks the
owner
property as true, because you've determined ahead of
time you are only returning the current user's content. The results of calling this method are shown in Figure
9-13
.
