枚举 TaskDeploymentDescriptorFactory.PartitionLocationConstraint

java.lang.Object

java.lang.Enum<TaskDeploymentDescriptorFactory.PartitionLocationConstraint>

org.apache.flink.runtime.deployment.TaskDeploymentDescriptorFactory.PartitionLocationConstraint

所有已实现的接口:

Serializable, Comparable<TaskDeploymentDescriptorFactory.PartitionLocationConstraint>

封闭类:

TaskDeploymentDescriptorFactory

public static enum TaskDeploymentDescriptorFactory.PartitionLocationConstraint
extends Enum<TaskDeploymentDescriptorFactory.PartitionLocationConstraint>

Defines whether the partition's location must be known at deployment time or can be unknown and, therefore, updated later.

MUST_BE_KNOWN

public static final TaskDeploymentDescriptorFactory.PartitionLocationConstraint MUST_BE_KNOWN

CAN_BE_UNKNOWN

public static final TaskDeploymentDescriptorFactory.PartitionLocationConstraint CAN_BE_UNKNOWN

方法详细资料

values

public static TaskDeploymentDescriptorFactory.PartitionLocationConstraint[] 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 (TaskDeploymentDescriptorFactory.PartitionLocationConstraint c : TaskDeploymentDescriptorFactory.PartitionLocationConstraint.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 TaskDeploymentDescriptorFactory.PartitionLocationConstraint 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

fromJobType
