Package org.aoju.bus.core.lang.range

Class Range<T>

java.lang.Object

org.aoju.bus.core.lang.range.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:

Boundary

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.Stepper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。

Java 17+
