DownloadDb

from panda3d.core import DownloadDb
class DownloadDb

Bases: DTOOL_SUPER_BASE

A listing of files within multifiles for management of client-side synchronization with a server-provided set of files.

This class manages one copy of the database for the client, representing the files on the client system, and another copy for the server, representing the files the server has available.
