Field Detail

logger

protected transient Log logger

endpoint

protected ImmutableEndpoint endpoint

connector

protected final AbstractConnector connector

retryTemplate

protected RetryPolicyTemplate retryTemplate

connected

protected final WaitableBoolean connected

started

protected final WaitableBoolean started

disposed

protected final edu.emory.mathcs.backport.java.util.concurrent.atomic.AtomicBoolean disposed

startOnConnect

protected boolean startOnConnect

Indicates whether the receiver/dispatcher/requester should start upon connecting. This is necessary to support asynchronous retry policies, otherwise the start() method would block until connection is successful.

Constructor Detail

AbstractConnectable

public AbstractConnectable(ImmutableEndpoint endpoint)

Method Detail

disposeAndLogException

protected void disposeAndLogException()

exceptionThrown

public void exceptionThrown(Exception e)

Specified by:

exceptionThrown in interface ExceptionListener

handleException

public void handleException(Exception exception)

validate

public boolean validate()

activate

public void activate()

passivate

public void passivate()

initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

dispose

public void dispose()

Template method to destroy any resources held by the Message Dispatcher

Specified by:

dispose in interface Disposable

getConnector

public Connector getConnector()

getEndpoint

public ImmutableEndpoint getEndpoint()

connect

public final void connect()
                   throws Exception

Description copied from interface: Connectable

Make the connection to the underlying transport. The fact that this object is connected or not should have no influence on the lifecycle, especially the start / stop state if applicable.

Specified by:

connect in interface Connectable

Throws:

Exception

validateConnection

public RetryContext validateConnection(RetryContext retryContext)

Description copied from interface: Connectable

Test whether the connector is able to connect to its resource(s). This will allow a retry policy to go into effect in the case of failure. Implementations must call either:

• RetryContext.setOk() when no problems found (or no validation required).
• RetryContext.setFailed(Throwable) with a root cause for a connection failure.

Callers should then check for RetryContext.isOk(). The failure, if any, will be provided via the RetryContext.getLastFailure().

Specified by:

validateConnection in interface Connectable

Returns:

same retry context with status info set and any failures populated

disconnect

public final void disconnect()
                      throws Exception

Description copied from interface: Connectable

Disconnect the from the underlying transport

Specified by:

disconnect in interface Connectable

Throws:

Exception

getConnectEventId

protected String getConnectEventId(ImmutableEndpoint endpoint)

isConnected

public final boolean isConnected()

Description copied from interface: Connectable

Determines if this object is connected or not

Specified by:

isConnected in interface Connectable

isDoThreading

protected boolean isDoThreading()

getConnectionDescription

public String getConnectionDescription()

Returns a string identifying the underlying resource

Specified by:

getConnectionDescription in interface Connectable

start

public final void start()
                 throws MuleException

Specified by:

start in interface Startable

Throws:

MuleException

stop
