Class ComputeIterator<T>

java.lang.Object

org.aoju.bus.core.collection.ComputeIterator<T>

Type Parameters:

T - 节点类型

All Implemented Interfaces:

Iterator<T>

Direct Known Subclasses:

CsvParser, LineIterator, SplitIterator

public abstract class ComputeIterator<T>
extends Object
implements Iterator<T>

带有计算属性的遍历器 通过继承此抽象遍历器，实现computeNext()计算下一个节点，即可完成节点遍历 当调用hasNext()时将此方法产生的节点缓存，直到调用next()取出 当无下一个节点时，须返回null表示遍历结束

Since:

JDK 1.8+

Version:

6.3.0
