Class ModCountMap<K,V>

java.lang.Object
de.xima.fc.common.collection.ModCountMap<K,V>
Type Parameters:
K - Type of the map keys.
V - Type of the map values.
All Implemented Interfaces:
Serializable, Map<K,V>
public final class ModCountMap<K,V> extends Object implements Map<K,V>, Serializable
A map that keeps track of the number of modifications made to it. The only guarantee is that the modification increases by some amount when the deque is modified. No guarantees are made about the exact amount by which the modification counter increases. This class is not thread-safe.
Since:
8.2.0
