<concept id="GUID-D96EE819-DEA9-5B1A-AA94-4AC065C73697" xml:lang="en"><title>Array
of same length elements, segmented buffer</title><shortdesc>Describes how elements of the same length are organised in the
array buffer.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
<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>
<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>
