CSCoreStore

The default CSDataStack instance to be used. If defaultStack is not set before the first time accessed, a default-configured CSDataStack will be created.

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

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

Asynchronously adds a CSSQLiteStore to the defaultStack. Migrations are also initiated by default.

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 defaultStack‘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 defaultStack‘s managed object model version.

Using the defaultStack, creates an CSObjectMonitor for the specified NSManagedObject. Multiple CSObjectObservers may then register themselves to be notified when changes are made to the NSManagedObject.

Using the defaultStack, 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.

Using the defaultStack, 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.

Using the defaultStack, creates a CSListMonitor for a sectioned 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.

Using the defaultStack, fetches the NSManagedObject instance in the transaction’s context from a reference created from a transaction or from a different managed object context.

Using the defaultStack, fetches the NSManagedObject instance in the transaction’s context from an NSManagedObjectID.

Using the defaultStack, fetches the NSManagedObject instances in the transaction’s context from references created from a transaction or from a different managed object context.

Using the defaultStack, fetches the NSManagedObject instances in the transaction’s context from a list of NSManagedObjectID.

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

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

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

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

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

Using the defaultStack, 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.

Using the defaultStack, 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.

Returns the defaultStack‘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 defaultStack‘s model.

Returns the NSEntityDescription for the specified NSManagedObject subclass from defaultStack‘s model.

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

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

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

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

Adds a CSInMemoryStore to the defaultStack and blocks until completion.

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

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

Using the defaultStack, begins a transaction asynchronously where NSManagedObject creates, updates, and deletes can be made.

Using the defaultStack, begins a transaction synchronously where NSManagedObject creates, updates, and deletes can be made.

Using the defaultStack, 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 defaultStack.
