Interface ApolloStore

All Known Implementing Classes:

NoOpApolloStore, RealApolloStore

public interface ApolloStore

ApolloStore exposes a thread-safe api to access a NormalizedCache. It also maintains a list of ApolloStore.RecordChangeSubscriber that will be notified with changed records. Most clients should have no need to directly interface with an ApolloStore.
