类 CopyOnWriteMultiset<E>

java.lang.Object

tv.danmaku.ijk.media.drm.util.CopyOnWriteMultiset<E>

类型参数:

E - The type of element being stored.

所有已实现的接口:

java.lang.Iterable<E>

public final class CopyOnWriteMultiset<E>
extends java.lang.Object
implements java.lang.Iterable<E>

An unordered collection of elements that allows duplicates, but also allows access to a set of unique elements.

This class is thread-safe using the same method as CopyOnWriteArrayList. Mutation methods cause the underlying data to be copied. elementSet() and iterator() return snapshots that are unaffected by subsequent mutations.

Iterating directly on this class reveals duplicate elements. Unique elements can be accessed via elementSet(). Iteration order for both of these is not defined.
