how to get all Map Names from Hazelcast client

[Mohan]

Hi All,

I'm writing a Java client program to remotely connect to a Hazelcast
cluster and clear the entries.

Have a doubt, how to get the list of Maps available. (Just Map names
would be fine), is there any API available in

Hazelcast client Jar to do that ?

Thanks,
Mohan

How about this:

Collection<Instance> instances =  hazelcastInstance.getInstances();

for(Instance instance: instances){

if(instance.getInstanceType().isMap()){

//do anything. hazelcastInstance can be hazelcast node or hazelcast client. Both will work.

}

}

         Collection<DistributedObject> instances =  client.getDistributedObjects();

        for(DistributedObject instance: instances){

        if ( instance.getServiceName().equals("hz:impl:mapService")){

        instance.destroy();

        }

        }

Hi,

From Hazelcast server, you can execute following code to clearthe entries.

private void removeMaps(){

Map<String,MapConfig> mapList = instance.getConfig().getMapConfigs();

logger.info("Removing Maps. Current size: "+mapList.size());

for (String name : mapList.keySet()) {

instance.getMap(name).clear();

logger.info("Size of map: "+instance.getMap(name).size());

}

logger.info("Removed Maps. Current size: "+mapList.size());
