I am a newbie for Hazelcast. I would like to know how can I list current lock in Hazelcast console?

For ex. assume that i open three console and i have taken 3 lock as follow:

m.lock object1
m.lock object2
m.lock object3

How can i get output like:

number of lock site: 3
locks: object1, object2, object3

Console is just a test app to simulate basic functionalities of hazelcast.

To see your lock instances following code will help you.

HazelcastInstance hzInstance = Hazelcast.newHazelcastInstance(null);
Collection<Instance> instances = hzInstance.getInstances();
Set<Instance> locks = new HashSet<Instance>();
for (Instance inst : instances) {
    if(inst.getInstanceType().equals(Instance.InstanceType.LOCK))
    locks.add(inst);
}
