枚举 EpochManager.ParallelMode

java.lang.Object

java.lang.Enum<EpochManager.ParallelMode>

org.apache.flink.runtime.asyncprocessing.EpochManager.ParallelMode

所有已实现的接口:

Serializable, Comparable<EpochManager.ParallelMode>

封闭类:

EpochManager

public static enum EpochManager.ParallelMode
extends Enum<EpochManager.ParallelMode>

This enum defines whether parallel execution between epochs is allowed. We should keep this internal and away from API module for now, until we could see the concrete need for PARALLEL_BETWEEN_EPOCH from average users.

枚举常量概要

枚举常量

枚举常量和说明
PARALLEL_BETWEEN_EPOCH Subsequent epochs can begin execution even if the previous epoch has not yet completed.
SERIAL_BETWEEN_EPOCH Subsequent epochs must wait until the previous epoch is completed before they can start.

方法概要

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

SERIAL_BETWEEN_EPOCH

public static final EpochManager.ParallelMode SERIAL_BETWEEN_EPOCH

Subsequent epochs must wait until the previous epoch is completed before they can start.

PARALLEL_BETWEEN_EPOCH

public static final EpochManager.ParallelMode PARALLEL_BETWEEN_EPOCH

Subsequent epochs can begin execution even if the previous epoch has not yet completed. Usually performs better than SERIAL_BETWEEN_EPOCH.

方法详细资料

values

public static EpochManager.ParallelMode[] 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 (EpochManager.ParallelMode c : EpochManager.ParallelMode.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 EpochManager.ParallelMode 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
