Provided Methods

unsafe fn createContextForIdentifier_parentContext_parentIdentifierPath( &self, identifier: &NSString, parent_context: &CLSContext, parent_identifier_path: &NSArray<NSString>, ) -> Option<Retained<CLSContext>>

where Self: Sized + Message,

Available on crate features CLSContext and CLSObject only.

Implement to return a new context with the supplied identifier as a child of the parent context.

This method is invoked for missing contexts in:

 -[CLSDataStore contextsMatchingIdentifierPath:completion:]

and

 -[CLSContext descendantMatchingIdentifierPath:completion:]

It will be called successively for each identifier in the path that is not found. This helps centralize context creation in one place.

Note: New contexts returned in this method are automatically saved.

Parameter identifier: Identifier for the new context.

Parameter parentContext: Parent of the new context.

Parameter parentIdentifierPath: Ordered list of identifiers leading to the parent context.

Returns: The new context for the supplied identifier. The new context is automatically saved.
