Properties
static pb::MessageParser< MPQuadraticConstraint >	Parser `[get]`

static pbr::MessageDescriptor	Descriptor `[get]`

pbc::RepeatedField< int >	VarIndex `[get]`
	Sparse representation of linear terms in the quadratic constraint, where term i is var_index[i] * coefficient[i]. `var_index` are variable indices w.r.t the "variable" field in MPModelProto, and should be unique.

	Must be finite.

pbc::RepeatedField< int >	Qvar1Index `[get]`
	Sparse representation of quadratic terms in the quadratic constraint, where term i is qvar1_index[i] * qvar2_index[i] * qcoefficient[i]. `qvar1_index` and `qvar2_index` are variable indices w.r.t the "variable" field in MPModelProto. `qvar1_index`, `qvar2_index` and `coefficients` must have the same size. If the same unordered pair (qvar1_index, qvar2_index) appears several times, the sum of all of the associated coefficients will be applied.
