A software example


The Exaile music player [j.mp/exaile] uses Flyweight to reuse objects (in this case, music tracks) that are identified by the same URL. There's no point in creating a new object if it has the same URL as an existing object, so the same object is reused to save resources [j.mp/exailefly].

Peppy, an XEmacs-like editor implemented in Python [j.mp/peppyp], uses the Flyweight pattern to store the state of a major mode status bar. That's because unless modified by the user, all status bars share the same properties [j.mp/peepyfly].
