Listening for Item Events
The Item Listener is used by the Hazelcast IQueue, ISet and IList interfaces.
To write an Item Listener class, you implement the ItemListener interface and its methods itemAdded and itemRemoved. These methods
are invoked when an item is added or removed.
The following is an example Item Listener class.
public class Sample implements ItemListener {
public static void main( String[] args ) {
Sample sample = new Sample();
HazelcastInstance hazelcastInstance = Hazelcast.newHazelcastInstance();
ISet<Price> set = hazelcastInstance.getSet( "default" );
set.addItemListener( sample, true );
Price price = new Price( 10, time1 )
set.add( price );
set.remove( price );
}
public void itemAdded( Object item ) {
System.out.println( "Item added = " + item );
}
public void itemRemoved( Object item ) {
System.out.println( "Item removed = " + item );
}
}
