<p><a class="el" href="../../d0/dce/class_m_utils_1_1_lazy.html" title="Lazy initialization template class. ">Lazy</a> initialization template class. </p>
<p>The lazy-initialized value of type T can be obtained from a <code><a class="el" href="../../d0/dce/class_m_utils_1_1_lazy.html" title="Lazy initialization template class. ">Lazy</a><T></code> instance by using the <code>operator*()</code>. Initialization of the value happens when the <code>operator*()</code> is called for the very first time, by invoking the <code>initializer</code> lambda-function that was passed to the constructor. The return value of the <code>initializer</code> lambda-function is then stored internally, so that any subsequent call to the <code>operator*()</code> <em>immediately</em> returns the previously created value.</p>
-<p><b>Note on thread-saftey:</b> This class is thread-safe in the sense that all calls to <code>operator*()</code> on the same <code><a class="el" href="../../d0/dce/class_m_utils_1_1_lazy.html" title="Lazy initialization template class. ">Lazy</a><T></code> instance, regardless from which thread, are guaranteed to return the exactly same value/object. Still, if the value has <em>not</em> been initialized yet <b>and</b> if multiple threads happen to call <code>operator*()</code> at the same time, then the <code>initializer</code> lambda-function <em>may</em> be invoked more than once (concurrently and by different threads). In that case, all but one return value of the <code>initializer</code> lambda-function are discarded, and all threads eventually obtain the same value/object. </p>
