<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 id="GUID-D3DF754C-E97D-5408-8229-8AD4E262981E">

</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>
