Method
AddExpression	Return type: DoubleLinearExpr& Arguments: const LinearExpr& exprs, double coeff = 1.0 Adds a linear expression to the double linear expression.
AddTerm	Return type: DoubleLinearExpr& Arguments: IntVar var, double coeff Adds a term (var * coeff) to the linear expression.
AddTerm	Return type: DoubleLinearExpr& Arguments: BoolVar var, double coeff
coefficients	Return type: const std::vector<double>& Returns the vector of coefficients.
constant	Return type: double Returns the constant term.
DebugString	Return type: std::string Arguments: const CpModelProto* proto = nullptr Debug string. See the documentation for LinearExpr::DebugString().
DoubleLinearExpr
DoubleLinearExpr	Return type: explicit Arguments: BoolVar var Constructs a linear expression from a Boolean variable. It deals with logical negation correctly.
DoubleLinearExpr	Return type: explicit Arguments: IntVar var Constructs a linear expression from an integer variable.
DoubleLinearExpr	Return type: explicit Arguments: double constant Constructs a constant linear expression.
IsConstant	Return type: const bool Returns true if the expression has no variable.
Sum	Return type: static DoubleLinearExpr Arguments: absl::Span<const IntVar> vars Constructs the sum of a list of variables.
Sum	Return type: static DoubleLinearExpr Arguments: absl::Span<const BoolVar> vars Constructs the sum of a list of Boolean variables.
variables	Return type: const std::vector<int>& Returns the vector of variable indices.
WeightedSum	Return type: static DoubleLinearExpr Arguments: absl::Span<const IntVar> vars, absl::Span<const double> coeffs Constructs the scalar product of variables and coefficients.
WeightedSum	Return type: static DoubleLinearExpr Arguments: absl::Span<const BoolVar> vars, absl::Span<const double> coeffs Constructs the scalar product of Boolean variables and coefficients.
