Class StreamingDataSourceBuilder

java.lang.Object

com.launchdarkly.sdk.android.integrations.StreamingDataSourceBuilder

All Implemented Interfaces:

ComponentConfigurer<DataSource>

public abstract class StreamingDataSourceBuilder
extends java.lang.Object
implements ComponentConfigurer<DataSource>

Contains methods for configuring the streaming data source.

By default, the SDK uses a streaming connection to receive feature flag data from LaunchDarkly. If you want to customize the behavior of the connection, create a builder with Components.streamingDataSource(), change its properties with the methods of this class, and pass it to LDConfig.Builder.dataSource(ComponentConfigurer):

     LDConfig config = new LDConfig.Builder()
         .dataSource(Components.streamingDataSource().initialReconnectDelayMillis(500))
         .build();
 

Note that this class is abstract; the actual implementation is created by calling Components.streamingDataSource().

Since:

3.3.0

Method Detail

backgroundPollIntervalMillis

public StreamingDataSourceBuilder backgroundPollIntervalMillis(int backgroundPollIntervalMillis)

Sets the interval between feature flag updates when the application is running in the background.

Even when configured to use streaming, the SDK will switch to polling when in the background (unless LDConfig.Builder.disableBackgroundUpdating(boolean) is set). This property determines how often polling will happen.

The default value is LDConfig.DEFAULT_BACKGROUND_POLL_INTERVAL_MILLIS; the minimum is LDConfig.MIN_BACKGROUND_POLL_INTERVAL_MILLIS.

Parameters:

backgroundPollIntervalMillis - the reconnect time base value in milliseconds

Returns:

the builder

initialReconnectDelayMillis

public StreamingDataSourceBuilder initialReconnectDelayMillis(int initialReconnectDelayMillis)

Sets the initial reconnect delay for the streaming connection.

The streaming service uses a backoff algorithm (with jitter) every time the connection needs to be reestablished. The delay for the first reconnection will start near this value, and then increase exponentially for any subsequent connection failures.

The default value is DEFAULT_INITIAL_RECONNECT_DELAY_MILLIS.

Parameters:

initialReconnectDelayMillis - the reconnect time base value in milliseconds

Returns:

the builder
