AddSelfToCoeffMapOrStack()

ortools.linear_solver.python.linear_solver_natural_api.SumArray.AddSelfToCoeffMapOrStack	(		self,
			coeffs,
			multiplier,
			stack )

Private function used by GetCoeffs() to delegate processing.

Implementation must either update coeffs or push to the stack a
sub-expression and the accumulated multiplier that applies to it.

Args:
  coeffs: A dictionary of variables' coefficients. It is a defaultdict that
      initializes the new values to 0 by default.
  multiplier: The current accumulated multiplier to apply to this
      expression.
  stack: A list to append to if the current expression is composed of
      sub-expressions. The elements of the stack are pair tuples
      (multiplier, linear_expression).

Reimplemented from ortools.linear_solver.python.linear_solver_natural_api.LinearExpr.
