Request service information. The information about the service is requested and the ServiceListener.resolveService method is called as soon as it is available. Usage note: Do not call this method from the AWT event dispatcher thread. You will make the user interface unresponsive.

Parameters:

type	full qualified service type, such as `_http._tcp.local.` .
name	unqualified service name, such as `foobar` .
persistent	if `true` ServiceListener.resolveService will be called whenever new new information is received.

void javax.jmdns.impl.JmDNSImpl.unregisterService ( ServiceInfo infoAbstract ) [inline, virtual]

Unregister a service. The service should have been registered. Note: Unregistered services will not disappear form the list of services immediately. According to the specification, when unregistering services we send goodbye packets and then wait 1s before purging the cache.
This is support for shared records that can be rescued by some other cooperation DNS.

 Clients receiving a Multicast DNS Response with a TTL of zero SHOULD NOT immediately delete the record from the cache, but instead record a TTL of 1 and then delete the record one second later.

Parameters:

info	service info to remove

The timer that triggers our announcements. We can't use the main timer object, because that could cause a deadlock where Prober waits on JmDNS.this lock held by close(), close() waits for us to finish, and we wait for Prober to give us back the timer thread so we can announce. (Patch from docbug in 2006-04-19 still wasn't patched .. so I'm doing it!) The source for random values. This is used to introduce random delays in responses.
