<p>This interface is implemented by objects which are thread safe (ie. can be used by several threads at
the same time). Before using an object from a thread, one has to call <a class="link" href="GdaLockable.html#gda-lockable-lock" title="gda_lockable_lock ()"><code class="function">gda_lockable_lock()</code></a> or
<a class="link" href="GdaLockable.html#gda-lockable-trylock" title="gda_lockable_trylock ()"><code class="function">gda_lockable_trylock()</code></a> and call <a class="link" href="GdaLockable.html#gda-lockable-unlock" title="gda_lockable_unlock ()"><code class="function">gda_lockable_unlock()</code></a> when the object is not used anymore.</p>
