<brief_description>
A singleton that manages the unique identifiers of all resources within a project.
</brief_description>
<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 [code]uid://[/code].
[ResourceUID] keeps track of all registered resource UIDs in a project, generates new UIDs, and converts between their string and integer representations.

<methods>
<method name="add_id">
<return type="void" />
<param index="0" name="id" type="int" />
<param index="1" name="path" type="String" />
<description>
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.
</description>
</method>
<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].
</description>
</method>
<method name="get_id_path" qualifiers="const">
<return type="String" />
<param index="0" name="id" type="int" />
<description>
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 [method has_id] beforehand.
</description>
</method>
<method name="has_id" qualifiers="const">
<return type="bool" />
<param index="0" name="id" type="int" />
<description>
Returns whether the given UID value is known to the cache.
</description>
</method>
<method name="id_to_text" qualifiers="const">
<return type="String" />
<param index="0" name="id" type="int" />
<description>
Converts the given UID to a [code]uid://[/code] string value.
</description>
</method>
<method name="remove_id">
<return type="void" />
<param index="0" name="id" type="int" />
<description>
Removes a loaded UID value from the cache.
Fails with an error if the UID does not exist, so be sure to check [method has_id] beforehand.
</description>
</method>
<method name="set_id">
<return type="void" />
<param index="0" name="id" type="int" />
<param index="1" name="path" type="String" />
<description>
Updates the resource path of an existing UID.
Fails with an error if the UID does not exist, so be sure to check [method has_id] beforehand, or use [method add_id] instead.
</description>
</method>
<method name="text_to_id" qualifiers="const">
<return type="int" />
<param index="0" name="text_id" type="String" />
<description>
Extracts the UID value from the given [code]uid://[/code] string.
