Class SelectorOptimizer

java.lang.Object

com.hazelcast.internal.networking.nonblocking.SelectorOptimizer

public final class SelectorOptimizer
extends Object

The SelectorOptimizer optimizes the Selector so less litter is being created. The Selector uses a HashSet, but this creates an object for every add of a selection key. With this SelectorOptimizer a SelectionKeysSet, which contains an an array, is being used since every key is going to be inserted only once. This trick comes from Netty.
