func RegisterFitPredicate 

func RegisterFitPredicate(name string, predicate algorithm.FitPredicate) string

RegisterFitPredicate registers a fit predicate with the algorithm registry. Returns the name with which the predicate was registered.

func RegisterFitPredicateFactory 

func RegisterFitPredicateFactory(name string, predicateFactory FitPredicateFactory) string

func RegisterGetEquivalencePodFunction(equivalenceFuncFactory EquivalencePodFuncFactory)

RegisterGetEquivalencePodFunction registers equivalenceFuncFactory to produce equivalence class for given pod.

func RegisterMandatoryFitPredicate added in v1.8.0 

func RegisterMandatoryFitPredicate(name string, predicate algorithm.FitPredicate) string

RegisterMandatoryFitPredicate registers a fit predicate with the algorithm registry, the predicate is used by kubelet, DaemonSet; it is always included in configuration. Returns the name with which the predicate was registered.

func RegisterPredicateMetadataProducerFactory added in v1.5.0 

func RegisterPredicateMetadataProducerFactory(factory PredicateMetadataProducerFactory)

func RegisterPriorityConfigFactory 

func RegisterPriorityConfigFactory(name string, pcf PriorityConfigFactory) string

func RegisterPriorityFunction 

func RegisterPriorityFunction(name string, function algorithm.PriorityFunction, weight int) string

DEPRECATED Use Map-Reduce pattern for priority functions. Registers a priority function with the algorithm registry. Returns the name, with which the function was registered.

func RegisterPriorityFunction2(
	name string,
	mapFunction algorithm.PriorityMapFunction,
	reduceFunction algorithm.PriorityReduceFunction,
	weight int) string

RegisterPriorityFunction2 registers a priority function with the algorithm registry. Returns the name, with which the function was registered. FIXME: Rename to PriorityFunctionFactory.
