Class AmqpAbstractResource<R extends JmsResource,E extends org.apache.qpid.proton.engine.Endpoint>

java.lang.Object

org.apache.qpid.jms.provider.amqp.AmqpAbstractResource<R,E>

Type Parameters:

R - The JmsResource type that describe this resource.

E - The AMQP Endpoint that this resource encapsulates.

All Implemented Interfaces:

AmqpEventSink, AmqpResource

Direct Known Subclasses:

AmqpConnection, AmqpConsumer, AmqpProducer, AmqpSession, AmqpTemporaryDestination, AmqpTransactionCoordinator

public abstract class AmqpAbstractResource<R extends JmsResource,E extends org.apache.qpid.proton.engine.Endpoint>
extends Object
implements AmqpResource

Abstract base for all AmqpResource implementations to extend. This abstract class wraps up the basic state management bits so that the concrete object don't have to reproduce it. Provides hooks for the subclasses to initialize and shutdown.

AmqpAbstractResource

public AmqpAbstractResource(R resourceInfo,
                            E endpoint)

Creates a new instance with the JmsResource provided, and sets the Endpoint to the given value.

Parameters:

resourceInfo - The JmsResource instance that this AmqpResource is managing.

endpoint - The Proton Endpoint instance that this object maps to.

AmqpAbstractResource

public AmqpAbstractResource(R resourceInfo,
                            E endpoint,
                            AmqpResourceParent parent)

Creates a new instance with the JmsResource provided, and sets the Endpoint to the given value.

Parameters:

resourceInfo - The JmsResource instance that this AmqpResource is managing.

endpoint - The Proton Endpoint instance that this object maps to.

parent - The parent of this resource (null if no parent).
