It can basically be used like a smart pointer class with the special feature that it references a different object in every thread. The underlying object will be created when it is referenced for the first time. See the <a href="Poco.NestedDiagnosticContext.html" title="class Poco::NestedDiagnosticContext">NestedDiagnosticContext</a> class for an example how to use this template. Every thread only has access to its own thread local data. There is no way for a thread to access another thread's local data. </p> </div> <h2>Member Summary</h2> <p><b>Member Functions: </b><a href="Poco.ThreadLocal.html#10897" title="Poco::ThreadLocal::get()">get</a>, <a href="Poco.ThreadLocal.html#10896" title="Poco::ThreadLocal::operator *()">operator *</a>, <a href="Poco.ThreadLocal.html#10895" title="Poco::ThreadLocal::operator->()">operator-></a></p> <h2>Constructors</h2> <h3><a name="10893">ThreadLocal</a> <img src="images/inline.gif" alt="inline" title="inline" style="vertical-align:baseline;" border="0" /> </h3> <p class="decl"><a href="Poco.ThreadLocal.html" title="class Poco::ThreadLocal">ThreadLocal</a>();</p> <div class="description"> <p></p> </div> <h2>Destructor</h2> <h3><a name="10894">~ThreadLocal</a> <img src="images/inline.gif" alt="inline" title="inline" style="vertical-align:baseline;" border="0" /> </h3> <p class="decl">~<a href="Poco.ThreadLocal.html" title="class Poco::ThreadLocal">ThreadLocal</a>();</p> <div class="description"> <p></p> </div> <h2>Member Functions</h2> <h3><a name="10897">get</a> <img src="images/inline.gif" alt="inline" title="inline" style="vertical-align:baseline;" border="0" /> </h3> <p class="decl">C & get();</p> <div class="description"> <p>Returns a reference to the underlying data object.
