Alle implementierten Schnittstellen:

Runnable

public class ReceivingSearch
extends ReceivingAsync<IncomingSearchRequest>

Handles reception of search requests, responds for local registered devices.

Waits a random time between 0 and the requested MX (maximum 120 seconds) before executing. Only waits if there are actually any registered local devices.

Extracts the search target, builds and sends the dozens of messages required by the UPnP specification, depending on the search target and what local devices and services are found in the Registry.
