枚举常量详细资料
-
FALSE
public static final LazyToOneOption FALSE
Eagerly load the association.
-
PROXY
public static final LazyToOneOption PROXY
Lazy, give back a proxy which will be loaded when the state is requested. This should be the preferred option.
-
NO_PROXY
public static final LazyToOneOption NO_PROXY
Lazy, give back the real object loaded when a reference is requested. Bytecode enhancement is mandatory for this option. Falls back toPROXYif the class is not enhanced. This option should be avoided unless you can't afford the use of proxies

方法详细资料
-
values
public static LazyToOneOption[] 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 (LazyToOneOption c : LazyToOneOption.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 LazyToOneOption 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
