Enum Constant Summary

Enum Constants

Enum Constant and Description
AFTER_STATEMENT Indicates that JDBC connection should be aggressively released after each SQL statement is executed.
AFTER_TRANSACTION Indicates that JDBC connections should be released after each transaction ends (works with both JTA-registered synch and HibernateTransaction API).
ON_CLOSE Indicates that connections should only be released when the Session is explicitly closed or disconnected; this is the legacy (Hibernate2 and pre-3.1) behavior.

Method Summary

Modifier and Type	Method and Description
static ConnectionReleaseMode	parse(String name) Alias for valueOf(String) using upper-case version of the incoming name.
static ConnectionReleaseMode	valueOf(String name) Returns the enum constant of this type with the specified name.
static ConnectionReleaseMode[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

AFTER_STATEMENT

public static final ConnectionReleaseMode AFTER_STATEMENT

Indicates that JDBC connection should be aggressively released after each SQL statement is executed. In this mode, the application must explicitly close all iterators and scrollable results. This mode may only be used with a JTA datasource.

AFTER_TRANSACTION

public static final ConnectionReleaseMode AFTER_TRANSACTION

Indicates that JDBC connections should be released after each transaction ends (works with both JTA-registered synch and HibernateTransaction API). This mode may not be used with an application server JTA datasource.

This is the default mode starting in 3.1; was previously ON_CLOSE.

ON_CLOSE

public static final ConnectionReleaseMode ON_CLOSE

Indicates that connections should only be released when the Session is explicitly closed or disconnected; this is the legacy (Hibernate2 and pre-3.1) behavior.

Method Detail

values

public static ConnectionReleaseMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ConnectionReleaseMode c : ConnectionReleaseMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ConnectionReleaseMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

parse

public static ConnectionReleaseMode parse(String name)

Alias for valueOf(String) using upper-case version of the incoming name.

Parameters:

name - The name to parse

Returns:

The matched enum value.
