<h2><a class='anchor' name='description'>Description</a></h2>
<p>OSCFunc (and its subclass <a href="./../Classes/OSCdef.html">OSCdef</a>) registers one or more functions to respond to an incoming OSC message which matches a specified OSC Address. Many of its methods are inherited from its superclass <a href="./../Classes/AbstractResponderFunc.html">AbstractResponderFunc</a>. OSCFunc supports pattern matching of wildcards etc. in incoming messages. For efficiency reasons you must specify that an OSCFunc will employ pattern matching by creating it with the <a href="#*newMatching">*newMatching</a> method, or by passing a matching dispatcher to <a href="#*new">*new</a>. For details on the Open Sound Control protocol, see <a href="http://opensoundcontrol.org/spec-1_0">http://opensoundcontrol.org/spec-1_0</a><h2><a class='anchor' name='classmethods'>Class Methods</a></h2>
