For example, given the class <codeph>TSimple</codeph> defined as:</p> <codeblock id="GUID-E705AC6E-6671-552D-90A3-6BEF66E30A0C" xml:space="preserve">    class TSimple
+          {

+          void InternalizeL(RReadStream&amp; aStream);
+          void ExternalizeL(RWriteStream&amp; aStream) const;
+          ...
+          TInt8     iInt8Value;
+          TInt64    iInt64Value;
+          TRect     iRectangle;

+          CBufSeg*  iSegBuffer;
+          }</codeblock> <p><codeph>ExternalizeL()</codeph> and <codeph>InternalizeL()</codeph> might be implemented as:</p> <codeblock id="GUID-F89A6EEB-FA20-5A2B-A3DB-33630212DD70" xml:space="preserve">void TSimple::ExternalizeL(RWriteStream&amp; aStream) const

+          aStream &lt;&lt;  iInt8Value;
+          aStream &lt;&lt;  iInt64Value;
+          aStream &lt;&lt;  iRectangle
+          aStream &lt;&lt;  iUid;
+          aStream &lt;&lt;  *iSegBuffer;
+          }</codeblock> <codeblock id="GUID-DABABB0C-435F-594C-9424-F27EBDC00F17" xml:space="preserve">void TSimple::InternalizeL(RReadStream&amp; aStream)
+          {
+          aStream &gt;&gt;  iInt8Value;

+          aStream &gt;&gt;  iUid;
+          aStream &gt;&gt;  *iSegBuffer;
+          }</codeblock> <p>The templated operators can also be used on an object of type <codeph>TSimple</codeph>. For example:</p> <codeblock id="GUID-326FFA1F-3614-5257-A3F9-1908F25E5DC8" xml:space="preserve">TSimple simple;
+...
+aStream &lt;&lt; simple;
+...</codeblock> <p>The <codeph>operator&lt;&lt;</codeph> results in call to <codeph>TSimple::ExternalizeL()</codeph> function and this, in turn, calls <codeph>operator&lt;&lt;</codeph> on <codeph>TSimple</codeph>'s data members.</p> </conbody></concept>
