com.hazelcast.core.ISet
Concurrent, distributed implementation of {@link Set}
This class is not a general-purpose Set implementation! While this class implements the Set interface, it intentionally violates Set's general contract, which mandates the use of the equals method when comparing objects. Instead of the equals method this implementation compares the serialized byte version of the objects.
