Class CKFetchRecordZoneChangesOperation

  • All Implemented Interfaces:
    NSObject
    public class CKFetchRecordZoneChangesOperation
extends CKDatabaseOperation
    This operation will fetch records changes across the given record zones For each @c previousServerChangeToken passed in with a @c CKFetchRecordZoneChangesConfiguration, only records that have changed since that anchor will be fetched. If this is your first fetch of a zone or if you wish to re-fetch all records within a zone, do not include a @c previousServerChangeToken. Change tokens are opaque tokens and clients should not infer any behavior based on their content.

      • fetchAllChanges

        public boolean fetchAllChanges()
        Determines if the opertaion should fetch all changes from the server before completing. When set to YES, this operation will send repeated requests to the server until all record changes have been fetched. @c recordZoneChangeTokensUpdatedBlock will be invoked periodically, to give clients an updated change token so that already-fetched record changes don't need to be re-fetched on a subsequent operation. @c recordZoneFetchCompletionBlock will only be called once and @c moreComing will always be NO. When set to NO, it is the responsibility of the caller to issue subsequent fetch-changes operations when @c moreComing is YES in a @c recordZoneFetchCompletionBlock invocation. [@c] fetchAllChanges is YES by default

      • fetchRecordZoneChangesCompletionBlock

        public CKFetchRecordZoneChangesOperation.Block_fetchRecordZoneChangesCompletionBlock_ret fetchRecordZoneChangesCompletionBlock()
        This block is called when the operation completes. [@c] serverChangeToken-s previously returned via a @c recordZoneChangeTokensUpdatedBlock or @c recordZoneFetchCompletionBlock invocation, along with the record changes that preceded it, are valid even if there is a subsequent @c operationError Each @c CKOperation instance has a private serial queue. This queue is used for all callback block invocations.

      • recordZoneChangeTokensUpdatedBlock

        public CKFetchRecordZoneChangesOperation.Block_recordZoneChangeTokensUpdatedBlock_ret recordZoneChangeTokensUpdatedBlock()
        Clients are responsible for saving this per-recordZone @c serverChangeToken and passing it in to the next call to @c CKFetchRecordZoneChangesOperation. Note that a fetch can fail partway. If that happens, an updated change token may be returned in this block so that already fetched records don't need to be re-downloaded on a subsequent operation. [@c] recordZoneChangeTokensUpdatedBlock will not be called after the last batch of changes in a zone; the @c recordZoneFetchCompletionBlock block will be called instead. The @c clientChangeTokenData from the most recent @c CKModifyRecordsOperation issued on this zone is also returned, or nil if none was provided. If the server returns a @c CKErrorChangeTokenExpired error, the @c serverChangeToken used for this record zone when initting this operation 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 serverChangeToken. [@c] recordZoneChangeTokensUpdatedBlock will not be called if @c fetchAllChanges is NO. Each @c CKOperation instance has a private serial queue. This queue is used for all callback block invocations.
