This process is encapsulated by the <codeph>InternalizeL()</codeph> member function of the class.</p> <p>A class always defines <codeph>InternalizeL()</codeph> as:</p> <codeblock id="GUID-D35F2448-0283-56CA-81CB-EEBD2666D3C3" xml:space="preserve">void InternalizeL(RReadStream&amp; aStream);</codeblock> <p>and uses the read stream interface class, <codeph>RReadStream</codeph>.</p> <p>Note that <codeph>InternalizeL()</codeph> is not virtual and there is no implication that a class that requires an <codeph>InternalizeL()</codeph> function must be derived from any particular base class.</p> </conbody></concept>
