+elements</title><shortdesc>Describes how to identify elements within arrays.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>Elements within arrays are identified by their logical position within
+the array.</p>
+<p>Elements can also be accessed by key.</p>
+<p>For all of the arrays <i>except</i>: <codeph>RArray&lt;class T&gt;</codeph>, <codeph>RPointerArray&lt;class T&gt;</codeph> and
+any of their specialisations, the key structure is defined independently of
+the array itself, using:</p>
+<ul>
+<li id="GUID-DD8F7A9A-5A95-59DC-A98B-D3F74CCFD1D9"><p>a <codeph>TKeyArrayFix</codeph> object
+for arrays of same length elements.</p> </li>
+<li id="GUID-BB94B0F3-E182-5A14-98DE-BEC9D150C91A"><p>a <codeph>TKeyArrayVar</codeph> object
+for arrays of variable length elements.</p> </li>
+<li id="GUID-2AD3D7F3-3C1C-51EE-ADB4-7EEE489F42D0"><p>a <codeph>TKeyArrayPak</codeph> object
+for arrays of packed (variable length) elements.</p> </li>
+</ul>
+<p>Accessing an element by key requires the appropriate <codeph>TKeyArrayFix</codeph>, <codeph>TKeyArrayVar</codeph> or <codeph>TKeyArrayPak</codeph> object to be constructed and passed to the appropriate array class member
+function.</p>
+<p>For the: <codeph>RArray&lt;class T&gt;</codeph>, <codeph>RPointerArray&lt;class T&gt;</codeph> arrays,
+keys are part of the array itself. These arrays also use the classes:</p>
+<ul>
+<li id="GUID-476F1A74-3EEA-5F2D-BCDD-1CE53949D087"><p><codeph>TLinearOrder&lt;class T&gt;</codeph> to
+define the ordering of two objects.</p> </li>
+<li id="GUID-2631B9C1-5716-5FF3-B248-E19E75BB212F"><p><codeph>TIdentityRelation&lt;class T&gt;</codeph> to
+define the comparison of two objects.</p> </li>
+</ul>
