org.hibernate

Field Summary

static ConnectionReleaseMode AFTER_STATEMENT
          Indicates that JDBC connection should be aggressively released after each SQL statement is executed.

static ConnectionReleaseMode AFTER_TRANSACTION
          Indicates that JDBC connections should be released after each transaction ends (works with both JTA-registered synch and HibernateTransaction API).

static 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 Summary

static ConnectionReleaseMode parse(String modeName)
          Determine the correct ConnectionReleaseMode instance based on the given name.

String toString()
          Override of Object.toString().

Field 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

toString

public String toString()

Override of Object.toString(). Returns the release mode name.

Returns:: The release mode name.

parse

public static ConnectionReleaseMode parse(String modeName)
                                   throws HibernateException

Determine the correct ConnectionReleaseMode instance based on the given name.

Parameters:: modeName - The release mode name.
Returns:: The appropriate ConnectionReleaseMode instance
Throws:: HibernateException - Indicates the modeName param did not match any known modes.
