<pre class="prototype">Class Waitable</pre>
<p>Actually, this class represents the interface exposed by synchronization structures to script. Objects derived from this class can be used in functions and methods in the group <a href="feathers_threading_waiting_funcs.html">Waitings</a>. Usually, the Waitable class is implemented by Structures, but any object providing a mean to be acquired, released and waited for a change in the acquirability state can be derived from this class. </p>
<p>Currently, only the <a href="feathers_threading_Waitable.html#release">Waitable.release</a> method is exposed to scripts; this means that scripts cannot create their own waitable objects, but only use those provided by this or other modules. </p>

<h2>Methods</h2><h3><a name="release">release</a></h3><p class="brief">Releases a structure acquired by a waiting function. </p>
<pre class="prototype">Waitable.release()</pre>
<p>Unless the nature of the acquired object is known, and that object is known not to require release, every acquired object must be explicitly released after a succesful wait. </p>
