 | |
| 		Singleton for managing a cache of resource UIDs within a project.
 | |
| 	</brief_description>
 | |
| 	<description>
 | |
| 		Resources can not only be referenced using their resource paths [code]res://[/code], but alternatively through a unique identifier specified via [code]uid://[/code].
 | |
| 		Using UIDs allows for the engine to keep references between resources intact, even if the files get renamed or moved.
 | |
| 		This singleton is responsible for keeping track of all registered resource UIDs of a project, generating new UIDs and converting between the string and integer representation.

 | |
| 				Adds a new UID value which is mapped to the given resource path.
 | |
| 				Fails with an error if the UID already exists, so be sure to check [method has_id] beforehand, or use [method set_id] instead.

 | |
| 		<method name="create_id">
 | |
| 			<return type="int" />
 | |
| 			<description>
 | |
| 				Generates a random resource UID which is guaranteed to be unique within the list of currently loaded UIDs.
 | |
| 				In order for this UID to be registered, you must call [method add_id] or [method set_id].
