Examples with HubChannel com.amplifyframework.hub.HubChannel used on opensource projects

Example 1 with HubChannel

use of com.amplifyframework.hub.HubChannel in project amplify-android by aws-amplify.

the class HubAccumulator method create.

/**
 * Creates a {@link HubAccumulator} that accumulates events arriving on a particular channel,
 * whose event name is the given enum value (as string). For example, the accumulator
 * created as below will match all events with name
 * {@link DataStoreChannelEventName#OUTBOX_MUTATION_PROCESSED}:
 *
 *   HubAccumulator.create(HubChannel.DATASTORE, DataStoreChannelEventName.PUBLISH_TO_CLOUD);
 *
 * @param channel Channel on which to listen for events
 * @param enumeratedEventName A enum value, the toString() of which is expected as the name of
 *                             a hub event. Only events with this name will be accumulated.
 * @param quantity Number of events to accumulate
 * @param <E> The type of enumeration
 * @return A HubAccumulator

Example 2 with HubChannel
