枚举 Boundedness

java.lang.Object

java.lang.Enum<Boundedness>

org.apache.seatunnel.api.source.Boundedness

所有已实现的接口:

Serializable, Comparable<Boundedness>

public enum Boundedness
extends Enum<Boundedness>

Used to define the boundedness of a source. In batch mode, the source is BOUNDED. In streaming mode, the source is UNBOUNDED.

枚举常量详细资料

BOUNDED

public static final Boundedness BOUNDED

A BOUNDED stream is a stream with finite records.

UNBOUNDED

public static final Boundedness UNBOUNDED

A UNBOUNDED stream is a stream with infinite records.

方法详细资料

values

public static Boundedness[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (Boundedness c : Boundedness.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static Boundedness valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
