Abstract base class for constraints of kinematic fits.
virtual double getValue() const =0
Returns the value of the constraint function.
BaseConstraint & operator=(const BaseConstraint &rhs)
Assignment.
virtual ~BaseConstraint()
Virtual destructor.
void setName(const char *name_)
Set object's name.
virtual const char * getName() const
Returns the name of the constraint.
virtual double getError() const
Returns the error on the value of the constraint.
BaseConstraint()
Creates an empty BaseConstraint object.
virtual std::ostream & print(std::ostream &os) const
print object to ostream
Abstract base class for different kinds of events.
