Class CKFetchDatabaseChangesOperation

  • All Implemented Interfaces:
    NSObject
    public class CKFetchDatabaseChangesOperation
extends CKDatabaseOperation
    CKFetchDatabaseChangesOperation This operation will fetch changes to record zones within a database If a change anchor from a previous @c CKFetchDatabaseChangesOperation is passed in, only the zones that have changed since that anchor will be returned. This per-database @c serverChangeToken is not to be confused with the per-recordZone @c serverChangeToken from @c CKFetchRecordZoneChangesOperation. If this is your first fetch or if you wish to re-fetch all zones, pass nil for the change token. Change token are opaque tokens and clients should not infer any behavior based on their content. [@c] CKFetchDatabaseChangesOperation is supported in a @c privateCloudDatabase and @c sharedCloudDatabase API-Since: 10.0

        Each @c CKOperation instance has a private serial queue. This queue is used for all callback block invocations. This block may share mutable state with other blocks assigned to this operation, but any such mutable state should not be concurrently used outside of blocks assigned to this operation.

      • fetchAllChanges

        public boolean fetchAllChanges()
        When set to YES, this operation will send repeated requests to the server until all record zone changes have been fetched. [@c] changeTokenUpdatedBlock will be invoked periodically, to give clients an updated change token so that already-fetched record zone changes don't need to be re-fetched on a subsequent operation. When set to NO, it is the responsibility of the caller to issue subsequent fetch-changes operations when moreComing is YES in a @c fetchDatabaseChangesCompletionBlock invocation. [@c] fetchAllChanges is @c YES by default Each @c CKOperation instance has a private serial queue. This queue is used for all callback block invocations Blocks assigned to this operation may share mutable state with other blocks assigned to this operation, but any such mutable state should not be concurrently used outside of blocks assigned to this operation.

      • fetchDatabaseChangesCompletionBlock

        @Nullable
public @Nullable CKFetchDatabaseChangesOperation.Block_fetchDatabaseChangesCompletionBlock_ret fetchDatabaseChangesCompletionBlock()
        This block is called when the operation completes. Clients are responsible for saving the change token at the end of the operation and passing it in to the next call to @c CKFetchDatabaseChangesOperation. If the server returns a @c CKErrorChangeTokenExpired error, the @c previousServerChangeToken value was too old and the client should toss its local cache and re-fetch the changes in this record zone starting with a nil @c previousServerChangeToken. If @c moreComing is true then the server wasn't able to return all the changes in this response. Another @c CKFetchDatabaseChangesOperation operation should be run with the @c previousServerChangeToken token from this operation. Each @c CKOperation instance has a private serial queue. This queue is used for all callback block invocations This block may share mutable state with other blocks assigned to this operation, but any such mutable state should not be concurrently used outside of blocks assigned to this operation.
