Class ConcurrentHashMap.ValuesView<K,​V>

  • All Implemented Interfaces:
    java.lang.Iterable<V>, java.util.Collection<V>
    Enclosing class:
    ConcurrentHashMap<K,​V>
    public static final class ConcurrentHashMap.ValuesView<K,​V>
extends java.lang.Object
implements java.util.Collection<V>
    A view of a ConcurrentHashMap as a Collection of values, in which additions are disabled. This class cannot be directly instantiated. See ConcurrentHashMap.values,

    The view's iterator is a "weakly consistent" iterator that will never throw ConcurrentModificationException, and guarantees to traverse elements as they existed upon construction of the iterator, and may (but is not guaranteed to) reflect any modifications subsequent to construction.
