Nested Classes

Modifier and Type	Class	Description
static final class	LinearSolver.Builder	Compared to invalid reference LinearSolver.StandardBuilder this builder: 1) Accepts inequality constraints 2) Has relaxed the requiremnt on the RHS to be non-negative (both equalities and inequalities)
static final class	LinearSolver.Configuration
static final class	LinearSolver.ModelIntegration
(package private) static final class	LinearSolver.NewIntegration	An integration to a new/alternative/experimental LP-solver.
(package private) static final class	LinearSolver.OldIntegration
