It is designed essentially as an ingredient for // 0011 // building function objects. // 0012 // // 0013 // Parameters can be connnected to one another. If a parameter is // 0014 // connected, it takes is value (and limits) from the parameter to which // 0015 // it is connected. // 0016 // When disconnected, it captures the values of the connected field before // 0017 // dropping the connection. An attempt to alter the values of the field // 0018 // while the Parameter is connected to another parameter will result in // 0019 // an obnoxious warning mesage. // 0020 // // 0021 //--------------------------------------------------------------------------// 0022 #ifndef Parameter_h 0023 #define Parameter_h 1 0024 0025 #include <string> 0026 #include <iostream> 0027 #include "CLHEP/GenericFunctions/AbsParameter.hh" 0028 0029 namespace Genfun { 0030 0031 /** 0032 * @author 0033 * @ingroup genfun 0034 */ 0035 class Parameter:public AbsParameter { 0036 0037 PARAMETER_OBJECT_DEF(Parameter) 0038 0039 public: 0040 0041 // Constructor. 0042 Parameter(std::string name, 0043 double value, 0044 double lowerLimit=-1e100, 0045 double upperLimit= 1e100); 0046 0047 // Copy constructor 0048 Parameter(const Parameter & right); 0049 0050 // Destructor 0051 virtual ~Parameter(); 0052 0053 // Assignment 0054 const Parameter & operator=(const Parameter &right); 0055 0056 // Accessor for the Parameter name 0057 const std::string & getName() const; 0058 0059 // Accessor for value 0060 virtual double getValue() const; 0061 0062 // Accessor for Lower Limit 0063 double getLowerLimit() const; 0064 0065 // Accessor for Upper Limit 0066 double getUpperLimit() const; 0067 0068 // Set Value 0069 void setValue(double value); 0070 0071 // Set Lower Limit 0072 void setLowerLimit(double lowerLimit); 0073 0074 // Set Upper Limit 0075 void setUpperLimit(double upperLimit); 0076 0077 // Take values + limits from some other parameter. 0078 void connectFrom(const AbsParameter * source); 0079 0080 // Extra lingual type information: 0081 virtual Parameter *parameter() {return this;} 0082 virtual const Parameter *parameter() const {return this;} 0083 0084 private: 0085 0086 std::string _name ; // name 0087 double _value; // value 0088 double _lowerLimit; // lower limit 0089 double _upperLimit; // upper limit 0090 const AbsParameter *_sourceParameter; // connection 0091 0092 }; 0093 std::ostream & operator << ( std::ostream & o, const Parameter &p); 0094 } // namespace Genfun 0095 0096 #endif
