Overview

RKObjectMappingDefinition 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 RKDynamicObjectMapping.

Tasks

  •   rootKeyPath

    The root key path for the receiver.

         property
  •   forceCollectionMapping

    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.

         property

Properties

forceCollectionMapping

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.

@property (nonatomic, assign) BOOL forceCollectionMapping

Discussion

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”: “[email protected]” }, “rachit”: { “id”: 5678", “email”: “[email protected]” } } }

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.

rootKeyPath

The root key path for the receiver.

@property (nonatomic, copy) NSString *rootKeyPath

Discussion

Root key paths are handled differently depending on the context in which the mapping is being used. If the receiver is used for object mapping, the rootKeyPath specifies a nested root dictionary that all attribute and relationship mappings will be considered relative to. When the mapping is used in a serialization context, the rootKeyPath specifies that the serialized content should be stored in a dictionary nested with the rootKeyPath as the key.
