Enum Constant Summary

Enum Constants

Enum Constant	Description
AFTER_STATEMENT	Indicates that the JDBC connection should be aggressively released after each SQL statement is executed.
AFTER_TRANSACTION	Indicates that the JDBC connection should be released after each transaction ends.
BEFORE_TRANSACTION_COMPLETION	Indicates that the JDBC connection should be released before each transaction commits or rolls back.
ON_CLOSE	Indicates that connections should only be released when the session is explicitly closed or disconnected.

Enum Constant Detail

AFTER_STATEMENT

public static final ConnectionReleaseMode AFTER_STATEMENT

Indicates that the 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.

BEFORE_TRANSACTION_COMPLETION

public static final ConnectionReleaseMode BEFORE_TRANSACTION_COMPLETION

Indicates that the JDBC connection should be released before each transaction commits or rolls back.

This works with both resource-local transactions and with JTA-registered synchronizations. It may be used with an application server JTA datasource.

AFTER_TRANSACTION

public static final ConnectionReleaseMode AFTER_TRANSACTION

Indicates that the JDBC connection should be released after each transaction ends.

This works with both resource-local transactions and with JTA-registered synchronizations. But it may not be used with an application server JTA datasource.

This is the default mode.

ON_CLOSE

public static final ConnectionReleaseMode ON_CLOSE

Indicates that connections should only be released when the session is explicitly closed or disconnected.

Prior to Hibernate 3.1, this was the default mode.

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 uppercase version of the incoming name.

Parameters:

name - The name to parse

Returns:

The matched enum value.

interpret

public static ConnectionReleaseMode interpret(Object setting)
