Classes
class	RoutingModel
struct	RoutingModel::StateDependentTransit
	What follows is relevant for models with time/state dependent transits. More...
struct	RoutingModel::CostClass
struct	RoutingModel::CostClass::DimensionCost

struct	RoutingModel::VehicleTypeContainer
	Struct used to sort and store vehicles by their type. More...
struct	RoutingModel::VehicleTypeContainer::VehicleClassEntry
class	RoutingModelVisitor
	Routing model visitor. More...
class	DisjunctivePropagator
	This class acts like a CP propagator: it takes a set of tasks given by their start/duration/end features, and reduces the range of possible values. More...
struct	DisjunctivePropagator::Tasks
	A structure to hold tasks described by their features. More...
struct	TravelBounds
class	GlobalVehicleBreaksConstraint
	GlobalVehicleBreaksConstraint ensures breaks constraints are enforced on all vehicles in the dimension passed to its constructor. More...

struct	TypeRegulationsChecker::TypePolicyOccurrence
class	TypeIncompatibilityChecker
	Checker for type incompatibilities. More...
class	TypeRequirementChecker
	Checker for type requirements. More...
class	TypeRegulationsConstraint
	The following constraint ensures that incompatibilities and requirements between types are respected. More...
class	SimpleBoundCosts
	A structure meant to store soft bounds and associated violation constants. More...
struct	SimpleBoundCosts::BoundCost
class	RoutingDimension
	Dimensions represent quantities accumulated at nodes along the routes. More...
struct	RoutingDimension::NodePrecedence
class	SweepArranger
	Class to arrange indices by by their distance and their angles from the depot. More...
class	VehicleTypeCurator
class	IntVarFilteredDecisionBuilder
	Decision builder building a solution using heuristics with local search filters to evaluate its feasibility. More...
class	IntVarFilteredHeuristic
	Generic filter-based heuristic applied to IntVars. More...

class	CheapestInsertionFilteredHeuristic
struct	CheapestInsertionFilteredHeuristic::StartEndValue
class	GlobalCheapestInsertionFilteredHeuristic

class	EvaluatorCheapestAdditionFilteredHeuristic
	A CheapestAdditionFilteredHeuristic where the notion of 'cheapest arc' comes from an arc evaluator. More...
class	ComparatorCheapestAdditionFilteredHeuristic
	A CheapestAdditionFilteredHeuristic where the notion of 'cheapest arc' comes from an arc comparator. More...
class	SavingsFilteredHeuristic
	Filter-based decision builder which builds a solution by using Clarke & Wright's Savings heuristic. More...
struct	SavingsFilteredHeuristic::SavingsParameters
class	SequentialSavingsFilteredHeuristic
class	ParallelSavingsFilteredHeuristic
class	ChristofidesFilteredHeuristic
	Christofides addition heuristic. More...
class	BasePathFilter
	Generic path-based filter class. More...
