Examples of com.hazelcast.core.MultiMap.containsKey()

com.hazelcast.core.MultiMap.containsKey()
Returns whether the multimap contains an entry with the key.

Warning:

This method uses hashCode and equals of binary form of the key, not the actual implementations of hashCode and equals defined in key's class.
@param key the key whose existence is checked. @return true if the multimap contains an entry with the key, false otherwise.
