枚举 DistributionPattern

java.lang.Object

java.lang.Enum<DistributionPattern>

org.apache.flink.runtime.jobgraph.DistributionPattern

所有已实现的接口:

Serializable, Comparable<DistributionPattern>

public enum DistributionPattern
extends Enum<DistributionPattern>

A distribution pattern determines, which sub tasks of a producing task are connected to which consuming sub tasks.

It affects how ExecutionVertex and IntermediateResultPartition are connected in EdgeManagerBuildUtil

枚举常量概要

枚举常量

枚举常量和说明
ALL_TO_ALL Each producing sub task is connected to each sub task of the consuming task.
POINTWISE Each producing sub task is connected to one or more subtask(s) of the consuming task.

枚举常量详细资料

ALL_TO_ALL

public static final DistributionPattern ALL_TO_ALL

Each producing sub task is connected to each sub task of the consuming task.

POINTWISE

public static final DistributionPattern POINTWISE

Each producing sub task is connected to one or more subtask(s) of the consuming task.

方法详细资料

values

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