Interface MappedCounter<T>

Type Parameters:

T - The type of the key for the mapped counter, often this will be String, but any type that can be used as key for a HashMap will work here.

All Known Implementing Classes:

ConcurrentMappedCounter, MappedCounterImpl

public interface MappedCounter<T>

Interface for a Collection which simply counts a number of items. This encapsulates all the boilerplate code for deciding if a map already contains the key.
