	<methods>
		<method name="get_extension">
			<return type="GDExtension" />
			<param index="0" name="path" type="String" />
			<description>
				Returns the [GDExtension] at the given file [param path], or [code]null[/code] if it has not been loaded or does not exist.
			</description>
		</method>
		<method name="get_loaded_extensions" qualifiers="const">
			<return type="PackedStringArray" />
			<description>
				Returns the file paths of all currently loaded extensions.
			</description>
		</method>
		<method name="is_extension_loaded" qualifiers="const">
			<return type="bool" />
			<param index="0" name="path" type="String" />
			<description>
				Returns [code]true[/code] if the extension at the given file [param path] has already been loaded successfully. See also [method get_loaded_extensions].
			</description>
		</method>
		<method name="load_extension">
			<return type="int" enum="GDExtensionManager.LoadStatus" />
			<param index="0" name="path" type="String" />
			<description>
				Loads an extension by absolute file path. The [param path] needs to point to a valid [GDExtension]. Returns [constant LOAD_STATUS_OK] if successful.
			</description>
		</method>
		<method name="load_extension_from_function">
			<return type="int" enum="GDExtensionManager.LoadStatus" />
			<param index="0" name="path" type="String" />
			<param index="1" name="init_func" type="const GDExtensionInitializationFunction*" />
			<description>
				Loads the extension already in address space via the given path and initialization function. The [param path] needs to be unique and start with [code]"libgodot://"[/code]. Returns [constant LOAD_STATUS_OK] if successful.
			</description>
		</method>
		<method name="reload_extension">
			<return type="int" enum="GDExtensionManager.LoadStatus" />
			<param index="0" name="path" type="String" />
			<description>
				Reloads the extension at the given file path. The [param path] needs to point to a valid [GDExtension], otherwise this method may return either [constant LOAD_STATUS_NOT_LOADED] or [constant LOAD_STATUS_FAILED].
				[b]Note:[/b] You can only reload extensions in the editor. In release builds, this method always fails and returns [constant LOAD_STATUS_FAILED].
			</description>
		</method>
		<method name="unload_extension">
			<return type="int" enum="GDExtensionManager.LoadStatus" />
			<param index="0" name="path" type="String" />
			<description>
				Unloads an extension by file path. The [param path] needs to point to an already loaded [GDExtension], otherwise this method returns [constant LOAD_STATUS_NOT_LOADED].
			</description>
		</method>

				[b]Note:[/b] This signal is only emitted in editor builds.
			</description>
		</signal>
		<signal name="extension_unloading">
			<param index="0" name="extension" type="GDExtension" />
