枚举常量详细资料

CREATE

public static final SchemaAutoTooling CREATE

Drop the schema and recreate it on SessionFactory startup.

CREATE_DROP

public static final SchemaAutoTooling CREATE_DROP

Drop the schema and recreate it on SessionFactory startup. Additionally, drop the schema on SessionFactory shutdown.

CREATE_ONLY

public static final SchemaAutoTooling CREATE_ONLY

Create the schema on SessionFactory startup.

DROP

public static final SchemaAutoTooling DROP

Drop the schema and don't recreate it.

UPDATE

public static final SchemaAutoTooling UPDATE

Update (alter) the schema on SessionFactory startup.

VALIDATE

public static final SchemaAutoTooling VALIDATE

Validate the schema on SessionFactory startup.

NONE

public static final SchemaAutoTooling NONE

Do not attempt to update nor validate the schema.

方法详细资料

values

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

interpret

public static SchemaAutoTooling interpret(String configurationValue)
