Class Range<T>

java.lang.Object

cn.hutool.core.lang.Range<T>

Type Parameters:

T - 生成范围对象的类型

All Implemented Interfaces:

Serializable, Iterable<T>, Iterator<T>

Direct Known Subclasses:

DateRange

public class Range<T>
extends Object
implements Iterable<T>, Iterator<T>, Serializable

范围生成器。根据给定的初始值、结束值和步进生成一个步进列表生成器
由于用户自行实现Range.Steper来定义步进，因此Range本身无法判定边界（是否达到end），需在step实现边界判定逻辑。

此类使用ReentrantReadWriteLock保证线程安全
