CSDataStack

Initializes a CSDataStack with default settings. CoreStore searches for .xcdatamodeld from the main NSBundle and loads an NSManagedObjectModel from it. An assertion is raised if the model could not be found.

Initializes a CSDataStack from the model with the specified modelName in the specified bundle.

Returns the stack’s model version. The version string is the same as the name of the version-specific .xcdatamodeld file.

Returns the entity name-to-class type mapping from the CSDataStack‘s model.

Returns the NSEntityDescription for the specified NSManagedObject subclass from stack’s model.

Creates an CSInMemoryStore with default parameters and adds it to the stack. This method blocks until completion.

CSSQLiteStore *storage = [dataStack addInMemoryStorageAndWaitAndReturnError:&error];

Creates an CSSQLiteStore with default parameters and adds it to the stack. This method blocks until completion.

CSSQLiteStore *storage = [dataStack addSQLiteStorageAndWaitAndReturnError:&error];

Adds a CSInMemoryStore to the stack and blocks until completion.

NSError *error;
CSInMemoryStore *storage = [dataStack
    addStorageAndWait: [[CSInMemoryStore alloc] initWithConfiguration: @"Config1"]
    error: &error];

Adds a CSSQLiteStore to the stack and blocks until completion.

NSError *error;
CSSQLiteStore *storage = [dataStack
    addStorageAndWait: [[CSSQLiteStore alloc] initWithConfiguration: @"Config1"]
    error: &error];

Asynchronously adds a CSInMemoryStore to the stack. Migrations are also initiated by default.

NSError *error;
NSProgress *migrationProgress = [dataStack 
    addInMemoryStorage:[CSInMemoryStore new]
    completion:^(CSSetupResult *result) {
        if (result.isSuccess) {
            // ...
        }
    }
    error: &error];

NSError *error;
NSProgress *migrationProgress = [dataStack
    addInMemoryStorage:[[CSSQLiteStore alloc] 
        initWithFileName:@"core_data.sqlite"
        configuration:@"Config1"]
    completion:^(CSSetupResult *result) {
        if (result.isSuccess) {
            // ...
        }
    }
    error: &error];

Migrates a CSSQLiteStore to match the CSDataStack‘s managed object model version. This method does NOT add the migrated store to the data stack.

Checks the migration steps required for the CSSQLiteStore to match the CSDataStack‘s managed object model version.

Creates a CSObjectMonitor for the specified NSManagedObject. Multiple ObjectObservers may then register themselves to be notified when changes are made to the NSManagedObject.

Creates a CSListMonitor for a list of NSManagedObjects that satisfy the specified fetch clauses. Multiple CSListObservers may then register themselves to be notified when changes are made to the list.

Asynchronously creates a CSListMonitor for a list of NSManagedObjects that satisfy the specified fetch clauses. Multiple CSListObservers may then register themselves to be notified when changes are made to the list. Since NSFetchedResultsController greedily locks the persistent store on initial fetch, you may prefer this method instead of the synchronous counterpart to avoid deadlocks while background updates/saves are being executed.

Creates a CSListMonitor for a sectioned list of NSManagedObjects that satisfy the specified fetch clauses. Multiple ListObservers may then register themselves to be notified when changes are made to the list.

Fetches the NSManagedObject instance in the transaction’s context from a reference created from a transaction or from a different managed object context.

Fetches the NSManagedObject instance in the transaction’s context from an NSManagedObjectID.

Fetches the NSManagedObject instances in the transaction’s context from references created from a transaction or from a different managed object context.

Fetches the NSManagedObject instances in the transaction’s context from a list of NSManagedObjectID.

Fetches the first NSManagedObject instance that satisfies the specified CSFetchClauses. Accepts CSWhere, CSOrderBy, and CSTweak clauses.

Fetches all NSManagedObject instances that satisfy the specified CSFetchClauses. Accepts CSWhere, CSOrderBy, and CSTweak clauses.

Fetches the number of NSManagedObjects that satisfy the specified CSFetchClauses. Accepts CSWhere, CSOrderBy, and CSTweak clauses.

Fetches the NSManagedObjectID for the first NSManagedObject that satisfies the specified CSFetchClauses. Accepts CSWhere, CSOrderBy, and CSTweak clauses.

Fetches the NSManagedObjectID for all NSManagedObjects that satisfy the specified CSFetchClauses. Accepts CSWhere, CSOrderBy, and CSTweak clauses.

Queries aggregate values as specified by the CSQueryClauses. Requires at least a CSSelect clause, and optional CSWhere, CSOrderBy, CSGroupBy, and CSTweak clauses.

A query differs from a fetch in that it only retrieves values already stored in the persistent store. As such, values from unsaved transactions or contexts will not be incorporated in the query result.

Queries a dictionary of attribute values as specified by the CSQueryClauses. Requires at least a CSSelect clause, and optional CSWhere, CSOrderBy, CSGroupBy, and CSTweak clauses.

A query differs from a fetch in that it only retrieves values already stored in the persistent store. As such, values from unsaved transactions or contexts will not be incorporated in the query result.

Begins a transaction asynchronously where NSManagedObject creates, updates, and deletes can be made.

Begins a transaction synchronously where NSManagedObject creates, updates, and deletes can be made.

Begins a child transaction where NSManagedObject creates, updates, and deletes can be made. This is useful for making temporary changes, such as partially filled forms.

To support undo methods such as -undo, -redo, and -rollback, use the -beginSafeWithSupportsUndo: method passing YES to the argument. Without undo support, calling those methods will raise an exception.

• prameter supportsUndo: -undo, -redo, and -rollback methods are only available when this parameter is YES, otherwise those method will raise an exception. Note that turning on Undo support may heavily impact performance especially on iOS or watchOS where memory is limited.

Refreshes all registered objects NSManagedObjects in the DataStack.
