de.caff.util.SimpleCounter

All Implemented Interfaces:

Counter

public final class SimpleCounter
extends java.lang.Object
implements Counter

Changeable integer wrapper, to be used as counter especially as map values. Note that as this is a mutable value, it is a very bad idea to use it as a map key. This class is not thread safe, see ThreadSafeCounter for a thread safe counter!
