Method Documentation

enumerate:withEnumerator:()

- (void TRCSchemaData) enumerate:		(id)	object
withEnumerator:		(id< TRCSchemaDataEnumerator >)	enumerator

Walk through all object structure and call appropriate methods from TRCSchemaDataEnumerator protocol in enumerator.

Used by TRCSchema to validate object values

modify:withModifier:()

- (id TRCSchemaData) modify:		(id)	object
withModifier:		(id< TRCSchemaDataModifier >)	modifier

Walk through all object structure to replace (transform, convert) some of object's values.

TRCSchemaDataModifier methods used to do that. Used by TRCConverter to convert some values using TRCValueTransformers and TRCObjectMappers.

cancel()

- (void TRCSchemaData) cancel

Cancels current process like enumeration or modifying (see methods above).

Called when enumerator or modifier found some error and wants to cancel process.

isCancelled()

- (BOOL TRCSchemaData) isCancelled

Tells if current process is cancelled.

This method must return YES after cancel method called.
