java.lang.Object org.jivesoftware.smack.PacketCollector
public class PacketCollector
Provides a mechanism to collect packets into a result queue that pass a
specified filter. The collector lets you perform blocking and polling
operations on the result queue. So, a PacketCollector is more suitable to
use than a PacketListener
when you need to wait for a specific
result.
Each packet collector will queue up to 2^16 packets for processing before older packets are automatically dropped.
