枚举 DateTimeUtils.TimeUnitRange

java.lang.Object

java.lang.Enum<DateTimeUtils.TimeUnitRange>

org.apache.flink.table.utils.DateTimeUtils.TimeUnitRange

所有已实现的接口:

Serializable, Comparable<DateTimeUtils.TimeUnitRange>

封闭类:

DateTimeUtils

public static enum DateTimeUtils.TimeUnitRange
extends Enum<DateTimeUtils.TimeUnitRange>

A range of time units. The first is more significant than the other (e.g. year-to-day) or the same as the other (e.g. month).

方法详细资料

values

public static DateTimeUtils.TimeUnitRange[] 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 (DateTimeUtils.TimeUnitRange c : DateTimeUtils.TimeUnitRange.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 DateTimeUtils.TimeUnitRange 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

Returns a TimeUnitRange with a given start and end unit.

参数:

startUnit - Start unit

endUnit - End unit

返回:

Time unit range, or null if not valid

monthly

public boolean monthly()

Whether this is in the YEAR-TO-MONTH family of intervals.
