Module: LaunchDarkly::Interfaces::DataSource

Defined in:

lib/ldclient-rb/interfaces.rb

Overview

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.

Instance Method Summary

• #initialized? ⇒ Boolean

  Checks whether the data source has finished initializing.

• #start ⇒ Concurrent::Event

  Puts the data source into an active state.

• #stop ⇒ Object

  Puts the data source into an inactive state and releases all of its resources.

Instance Method Details

#initialized? ⇒ Boolean

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

Returns:

• (Boolean) —

  true if initialization is complete

# File 'lib/ldclient-rb/interfaces.rb', line 132

def initialized?
end

#start ⇒ Concurrent::Event

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.

Returns:

• (Concurrent::Event) —

  an Event which will be set once initialization is complete

# File 'lib/ldclient-rb/interfaces.rb', line 142

def start
end

#stop ⇒ Object

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
