module LaunchDarkly::Interfaces::DataSource

Mixin that defines the required methods of a data source implementation. This is the component that delivers feature flag data from LaunchDarkly to the LDClient by putting the data in the {FeatureStore}. It is expected to run concurrently on its own thread.

The client has its own standard implementation, which uses either a streaming connection or polling depending on your configuration. Normally you will not need to use another one except for testing purposes. {FileDataSource} provides one such test fixture.

Public Instance Methods

initialized?() click to toggle source

Checks whether the data source has finished initializing. Initialization is considered done once it has received one complete data set from LaunchDarkly.

@return [Boolean] true if initialization is complete

# File lib/ldclient-rb/interfaces.rb, line 132
def initialized?
end
start() click to toggle source

Puts the data source into an active state. Normally this means it will make its first connection attempt to LaunchDarkly. If `start` has already been called, calling it again should simply return the same value as the first call.

@return [Concurrent::Event] an Event which will be set once initialization is complete

# File lib/ldclient-rb/interfaces.rb, line 142
def start
end
stop() click to toggle source

Puts the data source into an inactive state and releases all of its resources. This state should be considered permanent (`start` does not have to work after `stop`).

# File lib/ldclient-rb/interfaces.rb, line 149
def stop
