+<p>This is a <codeph>CArrayFixSeg&lt;class T&gt;</codeph> object whose elements:</p>
+<ul>
+<li id="GUID-F196DE9B-A500-5421-A5EF-679ACB613297"><p>all have the same length</p> </li>
+<li id="GUID-999B1623-7FFF-5F48-91BD-202BE4E46669"><p>are contained within
+a segmented array buffer; the elements are logically contiguous but are physically
+contiguous only within a segment.</p> </li>
+</ul>
+<p>A segmented buffer is implemented as a doubly linked list of equally sized
+cells allocated from the heap and is always extended by allocating a new segment
+and inserting it into the appropriate place in the list. A segmented array
+buffer is implemented using a <codeph>CBufSeg</codeph> object.</p>
+<p>The following diagram illustrates how elements are organised within the
+array buffer:</p>
+<fig id="GUID-D3DF754C-E97D-5408-8229-8AD4E262981E">
+<image href="GUID-1C14ECA4-057B-5591-A8E3-F7DB0325E5AE_d0e219380_href.png" placement="inline"/>
+</fig>
+<p>This kind of array is suitable for large arrays with a high
+turnover of elements.</p>
+<p>This class is immediately derived from the abstract template base class <codeph>CArrayFix&lt;class T&gt;</codeph> which
+is itself derived from the abstract non-templated base class <codeph>CArrayFixBase</codeph>. </p>
