枚举常量概要

枚举常量

枚举常量	说明
AGGREGATE	The collection elements are compositions.
BASIC	The collection elements are basic, simple values.
MANY_TO_ANY	The collection elements represent entity's in a multi-valued ANY mapping.
MANY_TO_MANY	The collection elements represent entity's in a many-to-many association.
ONE_TO_MANY	The collection elements represent entity's in a one-to-many association.

方法概要

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

枚举常量详细资料

BASIC

public static final PluralAttributeElementNature BASIC

The collection elements are basic, simple values.

AGGREGATE

public static final PluralAttributeElementNature AGGREGATE

The collection elements are compositions.

ONE_TO_MANY

public static final PluralAttributeElementNature ONE_TO_MANY

The collection elements represent entity's in a one-to-many association.

MANY_TO_MANY

public static final PluralAttributeElementNature MANY_TO_MANY

The collection elements represent entity's in a many-to-many association.

MANY_TO_ANY

public static final PluralAttributeElementNature MANY_TO_ANY

The collection elements represent entity's in a multi-valued ANY mapping.

方法详细资料

values

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

isAssociation

public boolean isAssociation()

isCascadeable

public boolean isCascadeable()
