+checking wrapper for fixed length C++ arrays</title><shortdesc>C++ arrays do not provide range checking so Symbian platform offers
+a thin wrapper to add this functionality to arrays.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The C++ language provides <i>fixed length</i> arrays.</p>
+<p>It is often convenient to use these arrays in applications whenever the
+number of elements is fixed and known at compile time.</p>
+<p>The main disadvantage of using C++ arrays is that there is no automatic
+checking of index value. This means that it is possible to write over data
+that lies beyond the end of the allocated array size, and to read invalid
+data from beyond the end of the array.</p>
+<p>The templated class <codeph>TFixedArray&lt;class T,TInt S&gt;</codeph>, is
+a thin wrapper for C++ arrays. The major benefits of using this class over
+a basic C++ array are the provision of range-checked indexing and support
+for object deletion. There is no runtime penalty for using this class if debug-only
+range-checking is used.</p>
+<p>The class can be embedded as a data member of <codeph>CBase</codeph>-derived
+objects. The class can also be used on the program stack.</p>
