## org.springframework.jms.connection
Class DelegatingConnectionFactory

    java.lang.Object
      org.springframework.jms.connection.DelegatingConnectionFactory

All Implemented Interfaces:
  ConnectionFactory, QueueConnectionFactory, TopicConnectionFactory, InitializingBean, SmartConnectionFactory

    public class DelegatingConnectionFactory

extends Object
implements SmartConnectionFactory, QueueConnectionFactory, TopicConnectionFactory, InitializingBean

`ConnectionFactory` implementation that delegates all calls to a given target `ConnectionFactory`, adapting specific `create(Queue/Topic)Connection` calls to the target ConnectionFactory if necessary (e.g. when running JMS 1.0.2 API based code against a generic JMS 1.1 ConnectionFactory, such as ActiveMQ's PooledConnectionFactory).

This class allows for being subclassed, with subclasses overriding only those methods (such as `createConnection()`) that should not simply delegate to the target ConnectionFactory.

Can also be defined as-is, wrapping a specific target ConnectionFactory, using the "shouldStopConnections" flag to indicate whether Connections obtained from the target factory are supposed to be stopped before closed. The latter may be necessary for some connection pools that simply return released connections to the pool, not stopping them while they sit in the pool.

Constructor Detail

### DelegatingConnectionFactory

    public DelegatingConnectionFactory()

Method Detail

### setTargetConnectionFactory

    public void setTargetConnectionFactory(ConnectionFactory targetConnectionFactory)

  Set the target ConnectionFactory that this ConnectionFactory should delegate to.

### getTargetConnectionFactory

    public ConnectionFactory getTargetConnectionFactory()

  Return the target ConnectionFactory that this ConnectionFactory delegates to.

### setShouldStopConnections

    public void setShouldStopConnections(boolean shouldStopConnections)

  Indicate whether Connections obtained from the target factory are supposed to be stopped before closed ("true") or simply closed ("false"). The latter may be necessary for some connection pools that simply return released connections to the pool, not stopping them while they sit in the pool.

  Default is "false", simply closing Connections.

    `ConnectionFactoryUtils.releaseConnection(javax.jms.Connection, javax.jms.ConnectionFactory, boolean)`

### afterPropertiesSet

    public void afterPropertiesSet()

  Description copied from interface: `InitializingBean`
  Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

  This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

  Specified by:
    `afterPropertiesSet` in interface `InitializingBean`

### createConnection

    public Connection createConnection()
                                throws JMSException

  Specified by:
    `createConnection` in interface `ConnectionFactory`
  Throws:
    `JMSException`

### createConnection

    public Connection createConnection(String username,
                                       String password)
                                throws JMSException

  Specified by:
    `createConnection` in interface `ConnectionFactory`
  Throws:
    `JMSException`

### createQueueConnection

    public QueueConnection createQueueConnection()
                                          throws JMSException

  Specified by:
    `createQueueConnection` in interface `QueueConnectionFactory`
  Throws:
    `JMSException`

### createQueueConnection

    public QueueConnection createQueueConnection(String username,
                                                 String password)
                                          throws JMSException

  Specified by:
    `createQueueConnection` in interface `QueueConnectionFactory`
  Throws:
    `JMSException`

### createTopicConnection

    public TopicConnection createTopicConnection()
                                          throws JMSException

  Specified by:
    `createTopicConnection` in interface `TopicConnectionFactory`
  Throws:
    `JMSException`

### createTopicConnection

    public TopicConnection createTopicConnection(String username,
                                                 String password)
                                          throws JMSException

  Specified by:
    `createTopicConnection` in interface `TopicConnectionFactory`
  Throws:
    `JMSException`

### shouldStop

    public boolean shouldStop(Connection con)

  Description copied from interface: `SmartConnectionFactory`
  Should we stop the Connection, obtained from this ConnectionFactory?

  Specified by:
    `shouldStop` in interface `SmartConnectionFactory`
  Parameters:
    `con` - the Connection to check
  Returns:
    whether a stop call is necessary

    `Connection.stop()`
