COError class documentation
COError : NSErrorOverview
- An aggregate error contains suberrors in -errors (a suberror can contain other suberrors).
- A validation error contains a validation issue in -validationResult .
COError is used by CoreObject validation support such as -[COObject validate] and COEditingContext commit methods such as -[COEditingContext commitWithIdentifier:metadata:undoTrack:error:] .
-[COError domain] returns kCOCoreObjectErrorDomain.

+ (id) errorWithErrors: (id
) suberrors Returns a new autoreleased error that includes suberrors.

- + (id) errorWithValidationResult: (ETValidationResult *)aResult
Returns a new autoreleased error based on a validation result.
-
+ (NSArray *) errorsWithValidationResults: (id
) errors Returns new autoreleased error array where every error corresponds to validation result.
-
+ (id) errorWithValidationResults: (id

Basic Properties
- - (NSArray *) errors
Returns the suberrors.
An error that reports a -validationResult will return always an empty array.
When the suberrors are validation errors, -code returns kCOValidationMultipleErrorsError.
- - (ETValidationResult *) validationResult
Returns a validation result.
An error that contains suberrors with -errors will always return nil.
When the validation result is not nil, -code returns kCOValidationError.
