Member Function Documentation

auto_ptr< Constraint_Intermed > hitfit::Constraint_Intermed_Labels::clone ( void  ) const

virtual

Clone function to copy the instance.

Implements hitfit::Constraint_Intermed.

Definition at line 276 of file Constraint_Intermed.cc.

References Constraint_Intermed_Labels().

{
  return auto_ptr<Constraint_Intermed> 
    (new Constraint_Intermed_Labels (*this));
}

bool hitfit::Constraint_Intermed_Labels::has_label ( int  label ) const

private

Test to see if label is used by this side of the mass constraint.

Parameters

label

The label for which to search.

Return:

true is this constraint use the label. false if this constraint doesn't use the label.

bool hitfit::Constraint_Intermed_Labels::has_labels ( int  ilabel, int  jlabel  ) const

virtual

Check the instance for reference of ilabel and jlabel.

Parameters

ilabel	The first label to test.
jlabel	The second label to test.

Return:

true if this instance references both labels ilabel and jlabel.
false if this instance doesn't reference both labels.

Constraint_Intermed& hitfit::Constraint_Intermed_Labels::operator= ( const Constraint_Intermed &  )

private

Disallow assignment by NOT defining the assignment operation.

void hitfit::Constraint_Intermed_Labels::print ( std::ostream &  s ) const

virtual

double hitfit::Constraint_Intermed_Labels::sum_mass_terms ( const Fourvec_Event &  ev ) const

virtual

Evaluate this half of the mass constraint, using the data in ev.

Parameters

ev	The event for which the mass constraint is to be evaluated.

Return:
