MREditorKey Class Reference

Inherits from	NSObject
Conforms to	NSCopying NSSecureCoding
Declared in	MREditorKey.h

Overview

MREditorKey represents a globally-unique identifier to an object created in the Meridian Editor. Objects created in the Editor can have multiple identifier components and this class helps locate an object based on the various components needed.

Here’s an example: A Meridian “Placemark” has an identifier, but it is only unique to the parent Map containing it. The Map also has an identifier, but it is only unique to the parent App containing it. The App has its own identifier, which is globally unique, and so that is the root key with a ‘nil’ parent.

Putting it all together:

placemarkKey.identifier = Placemark ID placemarkKey.parent.identifier = Map ID placemarkKey.parent.parent.identifier = App ID
