枚举 InputStatus

java.lang.Object

java.lang.Enum<InputStatus>

org.apache.flink.streaming.runtime.io.InputStatus

所有已实现的接口:

Serializable, Comparable<InputStatus>

@Internal
public enum InputStatus
extends Enum<InputStatus>

An InputStatus indicates one input state which might be currently available, not available or already finished. It is returned while calling PushingAsyncDataInput.emitNext(DataOutput).

枚举常量概要

枚举常量

枚举常量和说明
END_OF_INPUT Indicator that the input has reached the end of data.
MORE_AVAILABLE Indicator that more data is available and the input can be called immediately again to emit more data.
NOTHING_AVAILABLE Indicator that no data is currently available, but more data will be available in the future again.

方法概要

限定符和类型	方法和说明
static InputStatus	valueOf(String name) 返回带有指定名称的该类型的枚举常量。
static InputStatus[]	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。

方法详细资料

values

public static InputStatus[] 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 (InputStatus c : InputStatus.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 InputStatus 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
