方法概要

限定符和类型	方法	说明
String	getErrorMsg()	Obtains the error message of a KvStore database exception.
static KvStoreErrorCode	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。)
static KvStoreErrorCode[]	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 (KvStoreErrorCode c : KvStoreErrorCode.values()) System.out.println(c);
