枚举常量概要

枚举常量

枚举常量	说明
ISOLATE	Execution of the DDL must be isolated from any ongoing transaction
ISOLATE_AND_TRANSACT	As with ISOLATE the execution of the DDL must be isolated from any ongoing transaction.
NONE	No handling of transactions is needed

方法概要

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

从类继承的方法 java.lang.Object

枚举常量详细资料

NONE

public static final TempTableDdlTransactionHandling NONE

No handling of transactions is needed

ISOLATE

public static final TempTableDdlTransactionHandling ISOLATE

Execution of the DDL must be isolated from any ongoing transaction

ISOLATE_AND_TRANSACT

public static final TempTableDdlTransactionHandling ISOLATE_AND_TRANSACT

As with ISOLATE the execution of the DDL must be isolated from any ongoing transaction. However, here the "isolation" will also be transacted. Some databases require that the DDL happen within a transaction. This value covers such cases.

方法详细资料

values

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