Method
`coefficients`	Return type: `const std::vector<int64_t>&` Returns the vector of coefficients.
`constant`	Return type: `int64_t` Returns the constant term.
`DebugString`	Return type: `std::string` Arguments: `const CpModelProto* proto = nullptr`
`FromProto`	Return type: `static LinearExpr` Arguments: `const LinearExpressionProto& proto` Constructs a linear expr from its proto representation.
`IsConstant`	Return type: `const bool` Returns true if the expression has no variables.
`LinearExpr`	Creates an empty linear expression with value zero.
`LinearExpr`	Arguments: `BoolVar var` Constructs a linear expression from a Boolean variable. It deals with logical negation correctly.
`LinearExpr`	Arguments: `IntVar var` Constructs a linear expression from an integer variable.
`LinearExpr`	Arguments: `int64_t constant` Constructs a constant linear expression.
`Sum`	Return type: `static LinearExpr` Arguments: `absl::Span<const IntVar> vars` Constructs the sum of a list of variables.
`Sum`	Return type: `static LinearExpr` Arguments: `absl::Span<const BoolVar> vars` Constructs the sum of a list of Boolean variables.
`Term`	Return type: `static LinearExpr` Arguments: `IntVar var, int64_t coefficient` Constructs var * coefficient.
`Term`	Return type: `static LinearExpr` Arguments: `BoolVar var, int64_t coefficient` Constructs bool * coefficient.
`variables`	Return type: `const std::vector<int>&` Returns the vector of variable indices.
`WeightedSum`	Return type: `static LinearExpr` Arguments: `absl::Span<const IntVar> vars, absl::Span<const int64_t> coeffs` Constructs the scalar product of variables and coefficients.
`WeightedSum`	Return type: `static LinearExpr` Arguments: `absl::Span<const BoolVar> vars, absl::Span<const int64_t> coeffs` Constructs the scalar product of Boolean variables and coefficients.
