class fv::Value&lt; T &gt;</h3>

<p>A templated value. </p>
<p>In order to facilitate run-time creation of analysis routines, it is necessary to have some ability to get and store <em>values</em>. Values can either be directly taken from some original data source (i.e. <a class="el" href="classfv_1_1ObservedValue.html" title="A value supplied by the dataset, not derived. ">ObservedValue</a>), or they can be a function of some other set of values (i.e. <a class="el" href="classfv_1_1DerivedValue.html" title="A Value derived from some other Values, not directly from the dataset. ">DerivedValue</a>). They template class T of Value&lt;T&gt; is the type of thing that is returned upon calling <a class="el" href="classfv_1_1Value.html#a4cc70444ceaf5d7651922adf9b7beeff" title="Calculate, if necessary, and return the value held by this object. ">get_value()</a>. </p>
