Example

Consider the following parameter specification file:

   <PARAM id="bval" type="bool" default="no"/>
   <PARAM id="ival" type="int"/>
   <PARAM id="rval" type="real"/>
   <PARAM id="sval" type="string" default="ab cd"/>
   <PARAM id="rlist" type="real" list="yes"/>

These parameters may be read within a C++ task, as follows:

// include headers
   #include <param.h>
   #include <string>
   #include <vector>

// access parameters
   bool   bval = booleanParameter("bval");
   int    ival = intParameter("ival");
   double rval = realParameter("rval");
   string sval = stringParameter("sval");
   vector<double> rlist = realParameterList("rlist");

// The parameter list "rlist" may also be read as follows:
   vector<double> rlist;
   int n = parameterCount("rlist");
   for(int i=0; i<n; i++)
       rlist.push_back(realParameter("rlist",i));
