Inherits from TICDSOperation : NSOperation
Declared in TICDSListOfPreviouslySynchronizedDocumentsOperation.h

Overview

The TICDSListOfPreviouslySynchronizedDocumentsOperation class describes a generic operation used by the TICoreDataSync framework to fetch a list of documents that have previously been synchronized for this application.

The operation carries out the following tasks:

  1. Get a list of document identifiers for available documents.
  2. Fetch the documentInfo dictionary for each document.
  3. Get the most recent synchronization date for each successfully-fetched document dictionary (the most recently modified file in RecentSyncs).

Operations are typically created automatically by the relevant sync manager.

You must use one of the subclasses of TICDSListOfPreviouslySynchronizedDocumentsOperation.

Instance Methods

buildArrayOfDocumentIdentifiers

Build an array of NSString document identifiers for all available, previously-synchronized documents.

- (void)buildArrayOfDocumentIdentifiers

Discussion

Call builtArrayOfDocumentIdentifiers: when the array is built.

Declared In

TICDSListOfPreviouslySynchronizedDocumentsOperation.h

builtArrayOfDocumentIdentifiers:

Pass back the assembled NSArray of NSString document identifiers.

- (void)builtArrayOfDocumentIdentifiers:(NSArray *)anArray

Parameters

anArray

The array of identifiers. Pass nil if an error occurred.

Discussion

If an error occurred, call setError: first, then specify nil for anArray.

Declared In

TICDSListOfPreviouslySynchronizedDocumentsOperation.h

fetchInfoDictionaryForDocumentWithSyncID:

Fetch the documentInfo dictionary for the document with the specified ID.

- (void)fetchInfoDictionaryForDocumentWithSyncID:(NSString *)aSyncID

Parameters

aSyncID

The synchronization identifier for the document.

Call fetchedInfoDictionary:forDocumentWithSyncID: for each document as it is fetched.

Declared In

TICDSListOfPreviouslySynchronizedDocumentsOperation.h

fetchLastSynchronizationDateForDocumentWithSyncID:

Fetch the last synchronization date for a document with the given synchronization ID.

- (void)fetchLastSynchronizationDateForDocumentWithSyncID:(NSString *)aSyncID

Parameters

aSyncID

The synchronization identifier for the document.

Call fetchedLastSynchronizationDate:forDocumentWithSyncID: when the date is fetched.

Declared In

TICDSListOfPreviouslySynchronizedDocumentsOperation.h

fetchedInfoDictionary:forDocumentWithSyncID:

Pass back the documentInfo dictionary for a given document sync identifier.

- (void)fetchedInfoDictionary:(NSDictionary *)anInfoDictionary forDocumentWithSyncID:(NSString *)aSyncID

Parameters

anInfoDictionary

The documentInfo dictionary, or nil if an error occurred.

aSyncID

The unique synchronization identifier of the given document.

Discussion

If an error occurred, call setError: first, then specify nil for anInfoDictionary.

Declared In

TICDSListOfPreviouslySynchronizedDocumentsOperation.h

fetchedLastSynchronizationDate:forDocumentWithSyncID:

Pass back the last synchronization date for a given document sync identifier.

- (void)fetchedLastSynchronizationDate:(NSDate *)aDate forDocumentWithSyncID:(NSString *)aSyncID

Parameters

aDate

The last synchronization date, or nil if an error occurred.

aSyncID

The unique synchronization identifier of the given document.

Discussion

If an error occurred, call setError: first, then specify nil for aDate.
