A helper class that unifies ivars handling.
Dividing implementation of ivars provider to a separate class allows us to abstract the logic and reuse it within any object that needs to handle ivars using composition. This breaks down the code into simpler and more managable chunks. It also simplifies ivars parsing and handling. To use the class, simply "plug" it to the class that needs to handle ivars and provide access through public interface.
The downside is that querrying code becomes a bit more verbose as another method or property needs to be sent before getting access to actual ivars data.
- initWithParentObject:
Initializes ivars provider with the given parent object.
- registerIvar:
Registers the given ivar to the providers data.
- mergeDataFromIvarsProvider:
Merges data from the given ivars provider.
ivars
The array of all registered ivars as GBIvarData instances in the order of registration.
Initializes ivars provider with the given parent object.
- (id)initWithParentObject:(id)parentReturns initialized object.
Initializes ivars provider with the given parent object.
The given parent object is set to each GBIvarData registered through registerIvar: . This is the designated initializer.
nil . GBIvarsProvider.hGBIvarsProvider.mMerges data from the given ivars provider.
- (void)mergeDataFromIvarsProvider:(GBIvarsProvider *)source GBIvarsProvider to merge from. Merges data from the given ivars provider.
This copies all unknown ivars from the given source to receiver and invokes merging of data for receivers ivars also found in source. It leaves source data intact.
GBIvarsProvider.hGBIvarsProvider.mRegisters the given ivar to the providers data.
- (void)registerIvar:(GBIvarData *)ivarRegisters the given ivar to the providers data.
If provider doesn't yet have the given ivar instance registered, the object is added to ivars list. If the same object is already registered, nothing happens.
Note: If another instance of the ivar with the same name is registered, an exception is thrown.
GBIvarsProvider.hGBIvarsProvider.m The array of all registered ivars as GBIvarData instances in the order of registration.
@property (readonly) NSArray *ivars The array of all registered ivars as GBIvarData instances in the order of registration.
