A filter constrains data with a filtering pattern.

Remarks
A filter constrains data with a filtering pattern.
Filters are usually created by android.widget.Filterable classes.
Filtering operations performed by calling #filter(CharSequence) or #filter(CharSequence, android.widget.Filter.FilterListener) are performed asynchronously. When these methods are called, a filtering request is posted in a request queue and processed later. Any call to one of these methods will cancel any previous non-executed filtering request.
