枚举 JobHistory.Keys

java.lang.Object

java.lang.Enum<JobHistory.Keys>

org.apache.hadoop.mapred.JobHistory.Keys

所有已实现的接口:

Serializable, Comparable<JobHistory.Keys>

封闭类:

JobHistory

public static enum JobHistory.Keys
extends Enum<JobHistory.Keys>

Job history files contain key="value" pairs, where keys belong to this enum. It acts as a global namespace for all keys.

方法详细资料

values

public static JobHistory.Keys[] 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 (JobHistory.Keys c : JobHistory.Keys.values())
    System.out.println(c);

valueOf

public static JobHistory.Keys 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。
