Interface TransactionalDataStore

public interface TransactionalDataStore
Interface for a data store that holds feature flags and related data received by the SDK. This interface supports updating the store transactionally using ChangeSets.

Ordinarily, the only implementation of this interface is the default in-memory implementation, which holds references to actual SDK data model objects.

Implementations must be thread-safe.
