		A class information repository.
	</brief_description>
	<description>
		Provides access to metadata stored for every available engine class.
		[b]Note:[/b] Script-defined classes with [code]class_name[/code] are not part of [ClassDB], so they will not return reflection data such as a method or property list. However, [GDExtension]-defined classes [i]are[/i] part of [ClassDB], so they will return reflection data.
