Server.getOnlinePlayers介绍

[英]Gets a view of all currently logged in players. This Collections#unmodifiableCollection(Collection) is a reused object, making some operations like Collection#size()zero-allocation.

The collection is a view backed by the internal representation, such that, changes to the internal state of the server will be reflected immediately. However, the reuse of the returned collection (identity) is not strictly guaranteed for future or all implementations. Casting the collection, or relying on interface implementations (like Serializable or List), is deprecated.

Iteration behavior is undefined outside of self-contained main-thread uses. Normal and immediate iterator use without consequences that affect the collection are fully supported. The effects following (non-exhaustive) Entity#teleport(Location), Player#setHealth(double), and Player#kickPlayer(String) are undefined. Any use of this collection from asynchronous threads is unsafe.

For safe consequential iteration or mimicking the old array behavior, using Collection#toArray(Object[]) is recommended. For making snapshots, ImmutableList#copyOf(Collection) is recommended.
[中]获取当前登录的所有玩家的视图。这个Collections#unmodifiableCollection（Collection）是一个可重用的对象，使Collection#size（）等操作成为零分配。
集合是一个由内部表示支持的视图，因此，对服务器内部状态的更改将立即反映出来。然而，并不能严格保证在将来或所有实现中重用返回的集合（标识）。不推荐使用强制转换集合或依赖接口实现（如Serializable或List）。
在自包含的主线程使用之外，迭代行为是未定义的。完全支持正常和立即使用迭代器，不会影响集合。未定义实体#远程传送（位置）、玩家#设置健康（双）和玩家#踢球玩家（字符串）后的效果（非详尽）。从异步线程使用此集合是不安全的。
为了安全地进行后续迭代或模仿旧的数组行为，建议使用Collection#toArray（Object[]）。制作快照时，建议使用ImmutableList#copyOf（Collection）。
