枚举常量概要

枚举常量

枚举常量	说明
AFTER_EVICT	A cascade point that occurs just after eviction of the parent entity from the session cache
AFTER_INSERT_BEFORE_DELETE	A cascade point that occurs just after the insertion of the parent entity and just before deletion
AFTER_INSERT_BEFORE_DELETE_VIA_COLLECTION	A cascade point that occurs just after the insertion of the parent entity and just before deletion, inside a collection
AFTER_LOCK	A cascade point that occurs just after refreshing a parent entity
AFTER_UPDATE	A cascade point that occurs just after update of the parent entity
BEFORE_FLUSH	A cascade point that occurs just before the session is flushed
BEFORE_INSERT_AFTER_DELETE	A cascade point that occurs just before the insertion of the parent entity and just after deletion
BEFORE_MERGE	A cascade point that occurs just before merging from a transient parent entity into the object in the session cache
BEFORE_REFRESH	A cascade point that occurs just after locking a transient parent entity into the session cache

方法概要

修饰符和类型	方法	说明
static CascadePoint	valueOf(String name)	返回带有指定名称的该类型的枚举常量。
static CascadePoint[]	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。

方法详细资料

values

public static CascadePoint[] 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 (CascadePoint c : CascadePoint.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 CascadePoint 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
