valueOf

public static HmilyAggregationType 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

isAggregationType

public static boolean isAggregationType(String aggregationType)

Is aggregation type.

参数:

aggregationType - aggregation type

返回:

is aggregation type or not
