Functions

func BucketUserToVariation

func BucketUserToVariation(vwoInstance schema.VwoInstance, userID string, campaign schema.Campaign) (schema.Variation, error)

BucketUserToVariation validates the User ID and returns Variation into which the User is bucketed in.

func EvaluateSegment

func EvaluateSegment(vwoInstance schema.VwoInstance, segments map[string]interface{}, options schema.Options) bool

EvaluateSegment function evaluates segmentation for the userID against the segments found inside the campaign.

func FindTargetedVariation

func FindTargetedVariation(vwoInstance schema.VwoInstance, userID string, campaign schema.Campaign, options schema.Options) (schema.Variation, error)

FindTargetedVariation function Identifies and retrives if there exists any targeted variation in the given campaign for given userID

func GetBucketValueForUser

func GetBucketValueForUser(vwoInstance schema.VwoInstance, userID string, maxValue,
	multiplier float64, campaign schema.Campaign) (uint32, int)

GetBucketValueForUser returns Bucket Value of the user by hashing the userId with murmur hash and scaling it down.

func GetBucketerVariation

func GetBucketerVariation(vwoInstance schema.VwoInstance, variations []schema.Variation, bucketValue int, userID, campaignKey string) (schema.Variation, error)

GetBucketerVariation function returns the Variation by checking the Start and End Bucket Allocations of each Variation

func GetVariation

func GetVariation(vwoInstance schema.VwoInstance, userID string, campaign schema.Campaign, goalIdentifier string, options schema.Options) (schema.Variation, string, error)

GetVariation function

	Returns variation for the user for given campaign
    This method achieves the variation assignment in the following way:
    1. First get variation from UserStorage, if variation is found in user_storage_data,
    return from there
    2. Evaluates white listing users for each variation, and find a targeted variation.
    3. If no targeted variation is found, evaluate pre-segmentation result
    4. Evaluate percent traffic
    5. If user becomes part of campaign assign a variation.
	6. Store the variation found in the user_storage

func GetVariationFromUserStorage

func GetVariationFromUserStorage(vwoInstance schema.VwoInstance, userID string, campaign schema.Campaign) (string, string)

GetVariationFromUserStorage function tries retrieving variation from user_storage

func GetWhiteListedVariationsList

func GetWhiteListedVariationsList(vwoInstance schema.VwoInstance, userID string, campaign schema.Campaign, options schema.Options) []schema.Variation

GetWhiteListedVariationsList function identifies all forced variations which are targeted by variation_targeting_variables

func IsUserPartOfCampaign

func IsUserPartOfCampaign(vwoInstance schema.VwoInstance, userID string, campaign schema.Campaign) bool

IsUserPartOfCampaign calculates if the provided userID should become part of the campaign or not

func PreEvaluateSegment

func PreEvaluateSegment(vwoInstance schema.VwoInstance, segments map[string]interface{}, options schema.Options, variationName string) bool

PreEvaluateSegment function evaluates segmentation for the userID against the segments found inside the campaign.

func SegmentEvaluator

func SegmentEvaluator(segments map[string]interface{}, customVariables map[string]interface{}) bool

SegmentEvaluator function evaluates segments to get the keys and values and perform appropriate functions
