ResourceUID
|
|
===========
|
|
|
|
**Inherits:** :ref:`Object<class_Object>`
|
|
|
|
A singleton that manages the unique identifiers of all resources within a project.

Description
|
|
-----------
|
|
|
|
Resource UIDs (Unique IDentifiers) allow the engine to keep references between resources intact, even if files are 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.

|
|
|
|
**INVALID_ID** = ``-1`` :ref:`🔗<class_ResourceUID_constant_INVALID_ID>`
|
|

Method Descriptions

-------------------
|

|
|
.. _class_ResourceUID_method_add_id:
|
|
|
|
.. rst-class:: classref-method
|
|
|
|
|void| **add_id**\ (\ id\: :ref:`int<class_int>`, path\: :ref:`String<class_String>`\ ) :ref:`🔗<class_ResourceUID_method_add_id>`
|
|
|
|
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.

.. _class_ResourceUID_method_create_id:

|
|
.. rst-class:: classref-method
|
|
|
|
:ref:`int<class_int>` **create_id**\ (\ ) :ref:`🔗<class_ResourceUID_method_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>`.

:ref:`String<class_String>` **get_id_path**\ (\ id\: :ref:`int<class_int>`\ ) |const| :ref:`🔗<class_ResourceUID_method_get_id_path>`
|
|
|
|
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.

:ref:`bool<class_bool>` **has_id**\ (\ id\: :ref:`int<class_int>`\ ) |const| :ref:`🔗<class_ResourceUID_method_has_id>`
|
|
|
|
Returns whether the given UID value is known to the cache.

|void| **remove_id**\ (\ id\: :ref:`int<class_int>`\ ) :ref:`🔗<class_ResourceUID_method_remove_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.

|void| **set_id**\ (\ id\: :ref:`int<class_int>`, path\: :ref:`String<class_String>`\ ) :ref:`🔗<class_ResourceUID_method_set_id>`
|
|
|
|
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.
