/**
`RKMapping` is an abstract class for objects defining RestKit object mappings. Its interface is common to all object mapping classes, including its concrete subclasses `RKObjectMapping` and `RKDynamicMapping`.
*/
@interface RKMapping : NSObject
///---------------------------------
/// @name Forcing Collection Mapping
///---------------------------------
/**
Forces the mapper to treat the mapped keyPath as a collection even if it does not return an array or a set of objects. This permits mapping where a dictionary identifies a collection of objects.
When enabled, each key/value pair in the resolved dictionary will be mapped as a separate entity. This is useful when you have a JSON structure similar to:
{ "users": {
"blake": { "id": 1234, "email": "blake@restkit.org" },
"rachit": { "id": 5678", "email": "rachit@restkit.org" }
}
}
By enabling `forceCollectionMapping`, RestKit will map "blake" => attributes and "rachit" => attributes as independent objects. This can be combined with `mapKeyOfNestedDictionaryToAttribute:` to properly map these sorts of structures.
@default `NO`
@see `mapKeyOfNestedDictionaryToAttribute`
