This process is encapsulated by the <codeph>ExternalizeL()</codeph> member function of the class.</p> <p>A class always defines <codeph>ExternalizeL()</codeph> as:</p> <codeblock id="GUID-68FB2FAA-6298-5BFA-B282-AFD4586D134C" xml:space="preserve">void ExternalizeL(RWriteStream&amp; aStream) const;</codeblock> <p>and uses the write stream interface class <codeph>RWriteStream</codeph>. </p> <p>Note that <codeph>ExternalizeL()</codeph> is not virtual and there is no implication that a class that requires an <codeph>ExternalizeL()</codeph> function must be derived from any particular base class.</p> </conbody></concept>
