Examples of org.jivesoftware.smack.PacketCollector

org.jivesoftware.smack.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 {@link PacketListener} when you need to wait for a specificresult.
Each packet collector will queue up a configured number of packets for processing before older packets are automatically dropped. The default number is retrieved by {@link SmackConfiguration#getPacketCollectorSize()}. @see Connection#createPacketCollector(PacketFilter) @author Matt Tucker
