Package com.cloudera.gertrude

Interface Summary

Interface	Description
Condition<S extends ExperimentState>	Determines a true or false value for a given ExperimentState.
ConditionFactory	Associates a set of names with implementations of the Condition interface and creates new instances of those implementations on request from a client.
ExperimentState	Container for all of the information about how to divert a request into experiments and what the values of experiment flags are for the current request.
FlagTypeParser<T>	Defines a strategy for converting the string form of a type back into an instance of that type.
FlagValueCalculator<T>	Logic for calculating the value of a named experiment flag for a given ExperimentState.
Layer	A horizontal slice of ExperimentSpace that contains subclasses of the Segment interface, which represent experiments and domains.
Segment	A vertical slice of buckets contained inside of a Layer that has associated Condition logic for diversion and overrides to the default flag values.

Class Summary

Class	Description
AbstractExperimentState	Abstract base class that implements the core functionality of the ExperimentState interface.
DiversionCriterion	A rule for diverting an ExperimentState into a Segment defined within the set of Layer instances in the current ExperimentSpace.
ExperimentFlag<T>	A named, typed parameter whose value for an ExperimentState can change depending on the experiments that the ExperimentState has been diverted into.
ExperimentFlagSettings	A mapping between experiment flag names and the rules for calculating the value of a flag.
ExperimentHandler	Manages experiment diversion for an ExperimentState based on the data contained in the current ExperimentSpace.
Experiments	A namespace for declaring, configuring, and accessing the core classes in the Gertrude framework.
ExperimentSpace	Defines the space of ExperimentFlagSettings, Layers and Segments that are available for an ExperimentState to be diverted into by the ExperimentHandler.
ExperimentSpace.Serialized	A container for the serialized form of the configuration data used to create a new ExperimentSpace.
ExperimentSpaceDeserializer	Converts an ExperimentSpace.Serialized instance to an ExperimentSpace and performs any other validation and verification checks that are necessary to ensure that the ExperimentSpace is ready to be used to serve requests.
ExperimentSpaceLoader	Manages loading and deserializing new ExperimentSpace instances and configuring the ExperimentHandler to start using them once they have been verified and validated.
FlagValue<T>	A utility class for tracking the value of a flag and its CacheLevel across a request.

Enum Summary

Enum	Description
Condition.CacheLevel	An indicator for how often the value of a Condition will change when the Condition.evaluate(ExperimentState) method is called repeatedly.
