RecentConnectionReader

from panda3d.net import RecentConnectionReader
class RecentConnectionReader

Bases: ConnectionReader

This flavor of ConnectionReader will read from its sockets and retain only the single most recent datagram for inspection by client code. It’s useful particularly for reading telemetry-type data from UDP sockets where you don’t care about getting every last socket, and in fact if the sockets are coming too fast you’d prefer to skip some of them.

This class will always create one thread for itself.
