All Implemented Interfaces:

DataSourceBuilder<Synchronizer>, DiagnosticDescription

public abstract class FDv2PollingSynchronizerBuilder
extends java.lang.Object
implements DataSourceBuilder<Synchronizer>, DiagnosticDescription

Contains methods for configuring the polling synchronizer.

This class is not stable, and not subject to any backwards compatibility guarantees or semantic versioning. It is in early access. If you want access to this feature please join the EAP. https://launchdarkly.com/docs/sdk/features/data-saving-mode

Example:

     LDConfig config = new LDConfig.Builder("my-sdk-key")
         .dataSystem(Components.dataSystem().custom()
             .initializers(DataSystemComponents.pollingInitializer())
             // DataSystemComponents.pollingSynchronizer() returns an instance of this builder.
             .synchronizers(DataSystemComponents.streamingSynchronizer(),
                 DataSystemComponents.pollingSynchronizer()
                     .pollInterval(Duration.ofMinutes(10)))
             .fDv1FallbackSynchronizer(DataSystemComponents.fDv1Polling()));

Method Detail

pollInterval

public FDv2PollingSynchronizerBuilder pollInterval(java.time.Duration pollInterval)

Sets the interval at which the SDK will poll for feature flag updates.

The default and minimum value is DEFAULT_POLL_INTERVAL. Values less than this will be set to the default.

Parameters:

pollInterval - the polling interval

Returns:

the builder

serviceEndpointsOverride

public FDv2PollingSynchronizerBuilder serviceEndpointsOverride(ServiceEndpointsBuilder serviceEndpointsOverride)

Sets overrides for the service endpoints. In typical usage, the synchronizer will use the commonly defined service endpoints, but for cases where they need to be controlled at the source level, this method can be used. This synchronizer will only use the endpoints applicable to it.

Parameters:

serviceEndpointsOverride - the service endpoints to override the base endpoints

Returns:

the builder

payloadFilter

public FDv2PollingSynchronizerBuilder payloadFilter(java.lang.String payloadFilter)

Sets the Payload Filter that will be used to filter the objects (flags, segments, etc.) from this synchronizer.

Parameters:

payloadFilter - the filter to be used

Returns:

the builder

describeConfiguration

public LDValue describeConfiguration(ClientContext context)

Description copied from interface: DiagnosticDescription

Used internally by the SDK to inspect the configuration.

Specified by:

describeConfiguration in interface DiagnosticDescription

Parameters:

context - allows access to the client configuration

Returns:

an LDValue or null
