Types

type DataDropper

type DataDropper interface {
	Drop(size int64) error
}

DataDropper interface is used by dependants who need to drop data from a collection

type EventMultiSdkConsumer

type EventMultiSdkConsumer interface {
	Count() int64
	PopNRaw(int64) ([]string, int64, error)
	PopNWithMetadata(n int64) ([]dtos.QueueStoredEventDTO, error)
}

EventMultiSdkConsumer defines the methods required to consume events from a stored shared by many sdks

type EventStorageConsumer

type EventStorageConsumer interface {
	Empty() bool
	PopN(n int64) ([]dtos.EventDTO, error)
}

EventStorageConsumer interface should be implemented by structs that offer popping impressions

type EventStorageProducer

type EventStorageProducer interface {
	Push(event dtos.EventDTO, size int) error
}

EventStorageProducer interface should be implemented by structs that accept incoming events

type EventsStorage

type EventsStorage interface {
	EventStorageConsumer
	EventStorageProducer
}

EventsStorage wraps consumer and producer interfaces

type Filter

type Filter interface {
	Add(data string)
	Contains(data string) bool
	Clear()
}

Filter interfaces

type ImpressionMultiSdkConsumer interface {
	Count() int64
	PopNRaw(int64) ([]string, int64, error)
	PopNWithMetadata(n int64) ([]dtos.ImpressionQueueObject, error)
}

ImpressionMultiSdkConsumer defines the methods required to consume impressions from a stored shared by many sdks

type ImpressionStorage

type ImpressionStorage interface {
	ImpressionStorageConsumer
	ImpressionStorageProducer
	ImpressionMultiSdkConsumer
}

ImpressionStorage wraps consumer & producer interfaces

type ImpressionStorageConsumer

type ImpressionStorageConsumer interface {
	Empty() bool
	PopN(n int64) ([]dtos.Impression, error)
}

ImpressionStorageConsumer interface should be implemented by structs that offer popping impressions

type ImpressionStorageProducer

type ImpressionStorageProducer interface {
	LogImpressions(impressions []dtos.Impression) error
}

ImpressionStorageProducer interface should be impemented by structs that accept incoming impressions

type ImpressionsCountConsumer

type ImpressionsCountConsumer interface {
	GetImpressionsCount() (*dtos.ImpressionsCountDTO, error)
}

ImpressionsCountProducer interface

type ImpressionsCountProducer

type ImpressionsCountProducer interface {
	RecordImpressionsCount(impressions dtos.ImpressionsCountDTO) error
}

ImpressionsCountProducer interface

type ImpressionsCountStorage

type ImpressionsCountStorage interface {
	ImpressionsCountConsumer
	ImpressionsCountProducer
}

type SegmentStorage

type SegmentStorage interface {
	SegmentStorageProducer
	SegmentStorageConsumer
}

SegmentStorage wraps consumer and producer interfaces

type SegmentStorageConsumer

type SegmentStorageConsumer interface {
	ChangeNumber(segmentName string) (int64, error)
	Keys(segmentName string) *set.ThreadUnsafeSet
	SegmentContainsKey(segmentName string, key string) (bool, error)
	SegmentKeysCount() int64
}

SegmentStorageConsumer interface should be implemented by all structs that ofer reading segments

type SegmentStorageProducer

type SegmentStorageProducer interface {
	Update(name string, toAdd *set.ThreadUnsafeSet, toRemove *set.ThreadUnsafeSet, changeNumber int64) error
	SetChangeNumber(segmentName string, till int64) error
}

SegmentStorageProducer interface should be implemented by all structs that offer writing segments

type SplitStorage

type SplitStorage interface {
	ChangeNumber() (int64, error)
	Update(toAdd []dtos.SplitDTO, toRemove []dtos.SplitDTO, changeNumber int64)
	KillLocally(splitName string, defaultTreatment string, changeNumber int64)
	SetChangeNumber(changeNumber int64) error
	All() []dtos.SplitDTO
	FetchMany(splitNames []string) map[string]*dtos.SplitDTO
	SegmentNames() *set.ThreadUnsafeSet // Not in Spec
	Split(splitName string) *dtos.SplitDTO
	SplitNames() []string
	TrafficTypeExists(trafficType string) bool
	GetNamesByFlagSets(sets []string) map[string][]string
	GetAllFlagSetNames() []string
}

SplitStorage wraps consumer & producer interfaces Note: Since go's interface composition does not (yet) support interface method overlap, extracting a common subset (.ChangeNumber()), embedding it in Both consumer & Producer, and then having a wide interface that embeds both (diamond composition), results in a compilation error. The only workaround so far is to explicitly define all the methods that make up the composed interface

type SplitStorageConsumer

type SplitStorageConsumer interface {
	ChangeNumber() (int64, error)
	All() []dtos.SplitDTO
	FetchMany(splitNames []string) map[string]*dtos.SplitDTO
	SegmentNames() *set.ThreadUnsafeSet // Not in Spec
	Split(splitName string) *dtos.SplitDTO
	SplitNames() []string
	TrafficTypeExists(trafficType string) bool
	GetNamesByFlagSets(sets []string) map[string][]string
	GetAllFlagSetNames() []string
}

SplitStorageConsumer should be implemented by structs that offer reading splits from storage

type SplitStorageProducer

type SplitStorageProducer interface {
	ChangeNumber() (int64, error)
	Update(toAdd []dtos.SplitDTO, toRemove []dtos.SplitDTO, changeNumber int64)
	KillLocally(splitName string, defaultTreatment string, changeNumber int64)
