- (Hash) cachedSnapshot (readonly)

A dictionary containing the values of the source object held in the persistent store coordinator layer. (read-only)

Returns:

- (Integer) newVersionNumber (readonly)

The new version number for the change. (read-only) A new version number of 0 means the object was deleted and the corresponding snapshot is nil.

Returns:

- (Hash) objectSnapshot (readonly)

A dictionary containing the values of the source object. (read-only)

Returns:

- (Integer) oldVersionNumber (readonly)

The old version number for the change. (read-only)

Returns:

- (Hash) persistedSnapshot (readonly)

A dictionary containing the values of the source object held in the persistent store. (read-only)

Returns:

- (NSManagedObject) sourceObject (readonly)

The source object for the conflict. (read-only)

Instance Method Details

- (Object) initWithSource(srcObject, newVersion:newvers, oldVersion:oldvers, cachedSnapshot:cachesnap, persistedSnapshot:persnap)

Initializes a merge conflict.

Parameters:

  • srcObject (NSManagedObject)

    The source object for the conflict.

  • newvers (Integer)

    The new version number for the change.A value of 0 means the object was deleted and the corresponding snapshot is nil.

  • oldvers (Integer)

    The old version number for the change.

  • cachesnap (Hash)

    A dictionary containing the values of srcObject held in the persistent store coordinator layer.

  • persnap (Hash)

    A dictionary containing the values of srcObject held in the persistent store.

Returns:

  • (Object)

    A merge conflict object initialized with the given parameters.
