枚举 JobType

java.lang.Object

java.lang.Enum<JobType>

org.apache.flink.runtime.jobgraph.JobType

所有已实现的接口:

Serializable, Comparable<JobType>

public enum JobType
extends Enum<JobType>

Enum to distinguish JobGraphs between batch and streaming, currently used by the scheduler.

枚举常量概要

枚举常量

枚举常量和说明
BATCH Batch jobs are finite jobs, potentially consisting of multiple pipelined regions.
STREAMING Streaming jobs are infinite jobs, consisting of one large pipelined region, not separated by any blocking data exchanges.

方法概要

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

枚举常量详细资料

BATCH

public static final JobType BATCH

Batch jobs are finite jobs, potentially consisting of multiple pipelined regions.

STREAMING

public static final JobType STREAMING

Streaming jobs are infinite jobs, consisting of one large pipelined region, not separated by any blocking data exchanges.

方法详细资料

values

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