Examples of com.hazelcast.core.IMap.addIndex()

com.hazelcast.core.IMap.addIndex()
r fields. // getters setter }
If you are querying your values mostly based on age and active then you should consider indexing these fields.
```
 IMap imap = Hazelcast.getMap("employees"); imap.addIndex("age", true);        // ordered, since we have ranged queries for this field imap.addIndex("active", false);    // not ordered, because boolean field cannot have range 
```
Index attribute should either have a getter method or be public. You should also make sure to add the indexes before adding entries to this map. @param attribute attribute of value @param ordered true if index should be ordered,false otherwise.
