<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>A function that can be added to a <a class="el" href="classhippodraw_1_1DataRep.html" title="The base class for data representations.">DataRep</a> and used in a fitter. </p>
<p>This is the base class for functions that can be added to a DataRep and used by a fitter. The initial value of the functions parameters can be set by a call to the <a class="el" href="classhippodraw_1_1FunctionBase.html#ac89ece7f0010b352e8d897f0a352f811" title="Sets the FunctionHelper so that the function can calculate a reasonable set of initial...">initialParameters()</a> member function. This function takes as argument a <a class="el" href="classhippodraw_1_1FunctionHelper.html" title="An abstract base class to help FunctionBase objects perform some operations.">FunctionHelper</a> which maybe connected to the data set. The function can make calls to the FunctionHelper to get some summaries from the data set and make an estimate of parameter values so that the function will at least appear on the DataRep if not come close to fitting it. This function must be implemented in a derived class.</p>
<p>The value of the function at a given value of the one dimensional coordinate <code>x</code>, or multi-dimensional coordinates as vector of doubles is obtained by a call to the overloaded member function <a class="el" href="classhippodraw_1_1FunctionBase.html#a3a71b677f013fdbc07bdf5dd65ee5f27" title="The function call operator.">operator()()</a>. This function must be implemented in a derived class.</p>
<p>To support a user interface, the name of the function may be obtained by a call to the <a class="el" href="classhippodraw_1_1FunctionBase.html#a11c23a386abb9eb8a42f0c2c2835d640" title="Returns the name of the function.">name()</a> member function and the name of the function's parameters from the <a class="el" href="classhippodraw_1_1FunctionBase.html#a5cd61d6494588c53f64ea1b4497a58e8" title="Returns a reference to a vector of parameter names.">parmNames()</a> member function. The values of the function's parameters can be obtained by a call to the <a class="el" href="classhippodraw_1_1FunctionBase.html#ab6d95a533aca7f862becee6eca151a68" title="Returns the values of the parameters as a vector.">getParameters()</a> member function. The number of parameters can be obtained by the size member function.</p>
<p>Internally, setting and receiving the parameters described above is done by the functions that take an iterator as an argument. The iterator skips over fixed parameters in both setting and receiving functions. This architecture is used to support the derived class <a class="el" href="classhippodraw_1_1LinearSumFunction.html" title="A function that can be used with a fitter.">LinearSumFunction</a>.</p>
<p>Derived classes need to implement a few pure virtual functions defined by this class.</p>
