Example 4 with WatchTargetChange

use of com.google.firebase.firestore.remote.WatchChange.WatchTargetChange in project firebase-android-sdk by firebase.

the class RemoteEventTest method createAggregator.

/**
 * Creates an aggregator initialized with the set of provided WatchChanges. Tests can add further
 * changes via `handleDocumentChange`, `handleTargetChange` and `handleExistenceFilterChange`.
 *
 * @param targetMap A map of query data for all active targets. The map must include an entry for
 *     every target referenced by any of the watch changes.
 * @param outstandingResponses The number of outstanding ACKs a target has to receive before it is
 *     considered active, or `noOutstandingResponses` if all targets are already active.
 * @param existingKeys The set of documents that are considered synced with the test targets as
 *     part of a previous listen. To modify this set during test execution, invoke
 *     `targetMetadataProvider.setSyncedKeys()`.
 * @param watchChanges The watch changes to apply before returning the aggregator. Supported
 *     changes are DocumentWatchChange and WatchTargetChange.
