<div class="textblock"><p>field specification and archetypical instance. </p>
<p>The FieldArchetype and its encapsulated element class contain pointers to the <a class="el" href="class_lin_box_1_1_field_abstract.html">FieldAbstract</a> and its encapsulated field element, respectively. FieldAbstract then uses virtual member functions to define operations on its encapsulated field element. This field element has no knowledge of the field properties being used on it which means the field object must supply these operations.</p>
<p>It does not contain elements zero and one because they can be created whenever necessary, although it might be beneficial from an efficiency stand point to include them. However, because of archetype use three, the elements themselves cannot be contained, but rather pointers to them. </p>
