Instance Method Details

#get_treatment(key, split_name, attributes = nil, split_data = nil, store_impressions = true, multiple = false) ⇒ String/Hash

obtains the treatment for a given feature

Parameters:

  • key (String/Hash) —

    user id or hash with matching_key/bucketing_key

  • split_name (String/Array) —

    name of the feature that is being validated or array of them

  • attributes (Hash) (defaults to: nil) —

    attributes to pass to the treatment class

  • split_data (Hash) (defaults to: nil) —

    split data, when provided this method doesn’t fetch splits_repository for the data

  • store_impressions (Boolean) (defaults to: true) —

    impressions aren’t stored if this flag is false

  • multiple (Hash) (defaults to: false) —

    internal flag to signal if method is called by get_treatments

Returns:

  • (String/Hash) —

    Treatment as String or Hash of treatments in case of array of features
