类 EvictingBoundedList<T>

java.lang.Object

org.apache.flink.runtime.util.EvictingBoundedList<T>

类型参数:

T - type of the list elements

所有已实现的接口:

Serializable, Iterable<T>

public class EvictingBoundedList<T>
extends Object
implements Iterable<T>, Serializable

This class implements a list (array based) that is physically bounded in maximum size, but can virtually grow beyond the bounded size. When the list grows beyond the size bound, elements are dropped from the head of the list (FIFO order). If dropped elements are accessed, a default element is returned instead.

The list by itself is serializable, but a full list can only be serialized if the values are also serializable.
