Examples of RabbitResourceHolder

org.springframework.amqp.rabbit.connection.RabbitResourceHolder
Rabbit resource holder, wrapping a RabbitMQ Connection and Channel. RabbitTransactionManager binds instances of this class to the thread, for a given Rabbit ConnectionFactory.
Note: This is an SPI class, not intended to be used by applications. @author Mark Fisher @author Dave Syer @author Gary Russell @see RabbitTransactionManager @see RabbitTemplate
