COCollectionTypeQuerying

COObject (COCollectionTypeQuerying)

COCollection is a abstract class that provides a common API to various concrete collection subclasses such as COGroup or COContainer.

AuthorsGenerated by qmathe
Declared inCOCollection.h

Default

- (BOOL) isGroup

Returns whether the receiver is a group or not.

    - (BOOL) isTag

    Returns whether the receiver is a tag or not.

    A tag is group that belongs to -[COEditingContext tagGroup] .

      - (BOOL) isContainer

      Returns whether the receiver is a container or not.

        - (BOOL) isLibrary

        Returns whether the receiver is a library or not.

        A library is a container.

          COSerialization

          COObject (COSerialization)

          Additions to convert inner objects into a "semi-serialized" representation.

          Overview

          COObjectGraphContext uses -storeItem to serialize a COObject into a COItem, and -setStoreItem: to deserialize in the reverse way.

          For debugging a serialization/deserialization cycle, see -roundTripValueForProperty: .

          NOTE: The rest of the API is unstable and incomplete.

          Default

          - (COItem *) storeItem

          The receiver serialized representation.

          -storeItem is used to serialize a COObject state and -setStoreItem: to deserialize a COObject state. COObjectGraphContext will call these accessors respectively at commit and loading times.

          At the end of -setStoreItem: -awakeFromDeserialization is called to recreate additional internal state based on the deserialization result. You must not touch and attempt to access or recreated relationships during -awakeFromDeserialization . For relationship restoration, you can implement -didLoadObjectGraph .

          -storeItem is also useful to inspect the serialized representation that goes into the store.

            - (void) setStoreItem: (COItem *)storeItem

            The receiver serialized representation.

            -storeItem is used to serialize a COObject state and -setStoreItem: to deserialize a COObject state. COObjectGraphContext will call these accessors respectively at commit and loading times.

            At the end of -setStoreItem: -awakeFromDeserialization is called to recreate additional internal state based on the deserialization result. You must not touch and attempt to access or recreated relationships during -awakeFromDeserialization . For relationship restoration, you can implement -didLoadObjectGraph .

            -storeItem is also useful to inspect the serialized representation that goes into the store.

                                  Testing

                                  - (id) roundTripValueForProperty: (NSString *)key

                                  Serializes the property value into the CoreObject serialized representation, then unserialize it back into a value that can be passed -setSerializedValue:forPropertyDescription:.

                                  The property value is retrieved with -serializedValueForPropertyDescription:, serialized using -serializedValueForValue: and deserialized using -valueForSerializedValue:ofType:propertyDescription:.
