<brief_description>

|
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.
