Method Detail

subscribe

public <T> void subscribe(@NotNull
                          com.apollographql.apollo.api.Subscription<?,T,?> subscription,
                          @NotNull
                          SubscriptionManager.Callback<T> callback)

Description copied from interface: SubscriptionManager

Starts provided subscription. Establishes connection to the subscription server if it was previously disconnected.

Specified by:

subscribe in interface SubscriptionManager

Parameters:

subscription - to start

callback - to be called on result

unsubscribe

public void unsubscribe(@NotNull
                        com.apollographql.apollo.api.Subscription subscription)

Description copied from interface: SubscriptionManager

Stops provided subscription. If there are no active subscriptions left, disconnects from the subscription server.

Specified by:

unsubscribe in interface SubscriptionManager

Parameters:

subscription - to stop

start

public void start()

Set the RealSubscriptionManager to a connectible state. It is safe to call this method at any time. Does nothing unless we are in the stopped state.

Specified by:

start in interface SubscriptionManager

stop

public void stop()

Unsubscribe from all active subscriptions, and disconnect the web socket. It will not be possible to add new subscriptions while the SubscriptionManager is stopping because we check the state in #doSubscribe(Subscription, Callback). We pass true to disconnect(boolean) because we want to disconnect even if, somehow, a new subscription is added while or after we are doing the doUnsubscribe(Subscription) loop.

Specified by:

stop in interface SubscriptionManager

Description copied from interface: SubscriptionManager
