the class AppSyncRequestFactory method buildSyncRequest.

/**
 * Builds the query document for base and delta sync.

 * against the provided time. Otherwise, if you provide a null lastSyncTime, a
 * request doc is generated for a base sync.
 * @param modelSchema Schema Class for which we want to sync.
 * @param lastSync The last time synced. If not provided, do a base query.
 *                 If provided, do a delta query.
 * @param <T> The type of objects we are syncing
 * @return A string which contains a GraphQL query doc for an base/delta sync
 * @throws DataStoreException On Failure to inspect
