ResourceUID
===========
**Inherits:** :ref:`Object<class_Object>`
A singleton that manages the unique identifiers of all resources within a project.
.. rst-class:: classref-introduction-group
Description
-----------
Resource UIDs (Unique IDentifiers) allow the engine to keep references between resources intact, even if files can renamed or moved. They can be accessed with ``uid://``.
\ **ResourceUID** keeps track of all registered resource UIDs in a project, generates new UIDs, and converts between their string and integer representations.

Constants
---------
.. _class_ResourceUID_constant_INVALID_ID:
.. rst-class:: classref-constant
**INVALID_ID** = ``-1``
The value to use for an invalid UID, for example if the resource could not be loaded.
Its text representation is ``uid://<invalid>``.

Method Descriptions
-------------------
.. _class_ResourceUID_method_add_id:
.. rst-class:: classref-method
void **add_id** **(** :ref:`int<class_int>` id, :ref:`String<class_String>` path **)**
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 :ref:`has_id<class_ResourceUID_method_has_id>` beforehand, or use :ref:`set_id<class_ResourceUID_method_set_id>` instead.
.. rst-class:: classref-item-separator
----
.. _class_ResourceUID_method_create_id:
.. rst-class:: classref-method
:ref:`int<class_int>` **create_id** **(** **)**
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 :ref:`add_id<class_ResourceUID_method_add_id>` or :ref:`set_id<class_ResourceUID_method_set_id>`.
.. rst-class:: classref-item-separator
----
.. _class_ResourceUID_method_get_id_path:
.. rst-class:: classref-method
:ref:`String<class_String>` **get_id_path** **(** :ref:`int<class_int>` id **)** |const|
Returns the path that the given UID value refers to.
Fails with an error if the UID does not exist, so be sure to check :ref:`has_id<class_ResourceUID_method_has_id>` beforehand.
.. rst-class:: classref-item-separator
----
.. _class_ResourceUID_method_has_id:
.. rst-class:: classref-method
:ref:`bool<class_bool>` **has_id** **(** :ref:`int<class_int>` id **)** |const|
Returns whether the given UID value is known to the cache.
.. rst-class:: classref-item-separator
----
.. _class_ResourceUID_method_id_to_text:
.. rst-class:: classref-method
:ref:`String<class_String>` **id_to_text** **(** :ref:`int<class_int>` id **)** |const|
Converts the given UID to a ``uid://`` string value.
.. rst-class:: classref-item-separator
----
.. _class_ResourceUID_method_remove_id:
.. rst-class:: classref-method
void **remove_id** **(** :ref:`int<class_int>` id **)**
Removes a loaded UID value from the cache.
Fails with an error if the UID does not exist, so be sure to check :ref:`has_id<class_ResourceUID_method_has_id>` beforehand.
.. rst-class:: classref-item-separator
----
.. _class_ResourceUID_method_set_id:
.. rst-class:: classref-method
void **set_id** **(** :ref:`int<class_int>` id, :ref:`String<class_String>` path **)**
Updates the resource path of an existing UID.
Fails with an error if the UID does not exist, so be sure to check :ref:`has_id<class_ResourceUID_method_has_id>` beforehand, or use :ref:`add_id<class_ResourceUID_method_add_id>` instead.
.. rst-class:: classref-item-separator
----
.. _class_ResourceUID_method_text_to_id:
.. rst-class:: classref-method
:ref:`int<class_int>` **text_to_id** **(** :ref:`String<class_String>` text_id **)** |const|
Extracts the UID value from the given ``uid://`` string.
