枚举常量概要

枚举常量

枚举常量和说明
JOINED A strategy in which fields that are specific to a subclass are mapped to a separate table than the fields that are common to the parent class, and a join is performed to instantiate the subclass.
SINGLE_TABLE A single table per class hierarchy
TABLE_PER_CLASS A table per concrete entity class

方法概要

限定符和类型	方法和说明
static InheritanceType	valueOf(String name) 返回带有指定名称的该类型的枚举常量。
static InheritanceType[]	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。

从类继承的方法 java.lang.Enum

clone, compareTo, equals, finalize, getDeclaringClass, hashCode, name, ordinal, toString, valueOf

枚举常量详细资料

SINGLE_TABLE

public static final InheritanceType SINGLE_TABLE

A single table per class hierarchy

TABLE_PER_CLASS

public static final InheritanceType TABLE_PER_CLASS

A table per concrete entity class

JOINED

public static final InheritanceType JOINED

A strategy in which fields that are specific to a subclass are mapped to a separate table than the fields that are common to the parent class, and a join is performed to instantiate the subclass.

方法详细资料

values

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