枚举 Fetch.Style

java.lang.Object

java.lang.Enum<Fetch.Style>

org.hibernate.engine.profile.Fetch.Style

所有已实现的接口:

Serializable, Comparable<Fetch.Style>

封闭类:

Fetch

public static enum Fetch.Style
extends Enum<Fetch.Style>

The type or style of fetch. For the moment we limit this to join and select, though technically subselect would be valid here as well; however, to support subselect here would require major changes to the subselect loading code (which is needed for other things as well anyway).

枚举常量概要

枚举常量

枚举常量	说明
JOIN	Fetch via a join
SELECT	Fetch via a subsequent select

方法概要

修饰符和类型	方法	说明
static Fetch.Style	parse(String name)	Parses a style given an externalized string representation
String	toString()
static Fetch.Style	valueOf(String name)	返回带有指定名称的该类型的枚举常量。
static Fetch.Style[]	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

JOIN

public static final Fetch.Style JOIN

Fetch via a join

SELECT

public static final Fetch.Style SELECT

Fetch via a subsequent select

方法详细资料

values

public static Fetch.Style[] 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 (Fetch.Style c : Fetch.Style.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 Fetch.Style 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

toString

public String toString()

覆盖:

toString 在类中 Enum<Fetch.Style>

parse

public static Fetch.Style parse(String name)

Parses a style given an externalized string representation

参数:

name - The externalized representation

返回:

The style; JOIN is returned if not recognized
