枚举常量概要

枚举常量

枚举常量	说明
DELAYED_ACQUISITION_AND_HOLD	The Connection will be acquired as soon as it is needed and then held until the Session is closed.
DELAYED_ACQUISITION_AND_RELEASE_AFTER_STATEMENT	The Connection will be acquired as soon as it is needed; it will be released after each statement is executed.
DELAYED_ACQUISITION_AND_RELEASE_AFTER_TRANSACTION	The Connection will be acquired as soon as it is needed; it will be released after each transaction is completed.
IMMEDIATE_ACQUISITION_AND_HOLD	The Connection will be acquired as soon as the Session is opened and held until the Session is closed.

方法概要

修饰符和类型	方法	说明
ConnectionAcquisitionMode	getAcquisitionMode()

static PhysicalConnectionHandlingMode	interpret(Object setting)
static PhysicalConnectionHandlingMode	interpret(ConnectionAcquisitionMode acquisitionMode, ConnectionReleaseMode releaseMode)
static PhysicalConnectionHandlingMode	valueOf(String name)	返回带有指定名称的该类型的枚举常量。
static PhysicalConnectionHandlingMode[]	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

IMMEDIATE_ACQUISITION_AND_HOLD

public static final PhysicalConnectionHandlingMode IMMEDIATE_ACQUISITION_AND_HOLD

The Connection will be acquired as soon as the Session is opened and held until the Session is closed. This is the only valid combination including immediate acquisition of the Connection

DELAYED_ACQUISITION_AND_HOLD

public static final PhysicalConnectionHandlingMode DELAYED_ACQUISITION_AND_HOLD

The Connection will be acquired as soon as it is needed and then held until the Session is closed. This is the original Hibernate behavior.

DELAYED_ACQUISITION_AND_RELEASE_AFTER_STATEMENT

public static final PhysicalConnectionHandlingMode DELAYED_ACQUISITION_AND_RELEASE_AFTER_STATEMENT

The Connection will be acquired as soon as it is needed; it will be released after each statement is executed.

DELAYED_ACQUISITION_AND_RELEASE_AFTER_TRANSACTION

public static final PhysicalConnectionHandlingMode DELAYED_ACQUISITION_AND_RELEASE_AFTER_TRANSACTION

The Connection will be acquired as soon as it is needed; it will be released after each transaction is completed.

方法详细资料

values

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

getAcquisitionMode

public ConnectionAcquisitionMode getAcquisitionMode()

getReleaseMode

public ConnectionReleaseMode getReleaseMode()

interpret

public static PhysicalConnectionHandlingMode interpret(Object setting)

interpret

public static PhysicalConnectionHandlingMode interpret(ConnectionAcquisitionMode acquisitionMode,
                                                       ConnectionReleaseMode releaseMode)
