Methods

Modifier and Type	Method and Description
void	assign(ExperimentState state, List<DiversionCriterion> diversionCriteria, Map<String,FlagValueCalculator<Object>> overrides, Set<Integer> newExperimentIds) Assign the given state to a Segment of this Layer based on the given diversionCriteria and update the overrides and set of newExperimentIds based on the settings in that Segment.
boolean	isLaunchLayer() Returns true if this is a launch layer instance, whose experiments have priority over other layers for overriding flag value calculations.

Method Detail

isLaunchLayer

public boolean isLaunchLayer()

Description copied from interface: Layer

Returns true if this is a launch layer instance, whose experiments have priority over other layers for overriding flag value calculations.

Specified by:

isLaunchLayer in interface Layer

Returns:

true if this is a launch layer

assign

public void assign(ExperimentState state,
          List<DiversionCriterion> diversionCriteria,
          Map<String,FlagValueCalculator<Object>> overrides,
          Set<Integer> newExperimentIds)

Description copied from interface: Layer

Assign the given state to a Segment of this Layer based on the given diversionCriteria and update the overrides and set of newExperimentIds based on the settings in that Segment.

Specified by:

assign in interface Layer

Parameters:

state - the ExperimentState undergoing diversion

diversionCriteria - the configured DiversionCriterion applied to the state

overrides - the current set of overrides to the default FlagValueCalculator instances

newExperimentIds - the list of new experiment ids this state will be added to
