Method Detail

registerListener

MessageReceiver registerListener(Service service,
                                 InboundEndpoint endpoint)
                                 throws Exception

This creates a MessageReceiver associated with this endpoint and registers it with the connector

Parameters:

service - the listening service

endpoint - the endpoint contains the listener endpointUri on which to listen on.

Throws:

Exception - if the MessageReceiver cannot be created or the Receiver cannot be registered

unregisterListener

void unregisterListener(Service service,
                        InboundEndpoint endpoint)
                        throws Exception

Parameters:

service - the listening service

endpoint - the associated endpointDescriptor with the listener

Throws:

Exception - if the listener cannot be unregistered. If a listener is not associated with the given endpoint this will not throw an exception

isStarted

boolean isStarted()

Returns:

true if the endpoint is started

isConnected

boolean isConnected()

isDisposed

boolean isDisposed()

Returns:

false if the connector is alive and well or true if the connector is being destroyed

getMessageAdapter

MessageAdapter getMessageAdapter(Object message)
                                 throws MuleException

Gets a MessageAdapter from the connector for the given message (data)

Parameters:

message - the data with which to initialise the MessageAdapter

Returns:

the MessageAdapter for the endpoint

Throws:

MessageTypeNotSupportedException - if the message parameter is not supported

MuleException - if there is a problem creating the Adapter

See Also:

MessageAdapter

getProtocol

String getProtocol()

Returns:

the primary protocol name for endpoints of this connector

supportsProtocol

boolean supportsProtocol(String protocol)

Returns:

true if the protocol is supported by this connector.

setExceptionListener

void setExceptionListener(ExceptionListener listener)

Parameters:

listener - the exception strategy to use with this endpoint

See Also:

ExceptionListener

getExceptionListener

ExceptionListener getExceptionListener()

Returns:

the Exception stategy used by the endpoint

See Also:

ExceptionListener

handleException

void handleException(Exception exception)

Parameters:

exception - the exception that was caught

setDispatcherFactory

void setDispatcherFactory(MessageDispatcherFactory factory)

The dispatcher factory is used to create a message dispatcher of the current request

Parameters:

factory - the factory to use when a dispatcher request is madr

getDispatcherFactory

MessageDispatcherFactory getDispatcherFactory()

The dispatcher factory is used to create a message dispatcher of the current request

Returns:

the factory to use when a dispatcher request is madr

setRequesterFactory

void setRequesterFactory(MessageRequesterFactory factory)

The requester factory is used to create a message requester of the current request

Parameters:

factory - the factory to use when a request is made

getRequesterFactory

MessageRequesterFactory getRequesterFactory()

The requester factory is used to create a message requester of the current request

Returns:

the factory to use when a request is made

isResponseEnabled

boolean isResponseEnabled()

isSyncEnabled

boolean isSyncEnabled(String protocol)

Used to define is this connectors endpoints' should be synchronous by default rather than using Mule's instance wide default. The endpoint is passed through to this method so that transports like Axis/CXF can determine if synchronous should be default depending on the endpoint transport e.g. http/vm/jms etc.

ImmutableEndpoint.isSynchronous()

dispatch

void dispatch(OutboundEndpoint endpoint,
              MuleEvent event)
              throws DispatchException

Dispatches an event from the endpoint to the external system

Parameters:

event - The event to dispatch

Throws:

DispatchException - if the event fails to be dispatched

request

@Deprecated
MuleMessage request(String uri,
                               long timeout)
                    throws Exception

Deprecated. Use request(ImmutableEndpoint endpoint, long timeout)

Make a specific request to the underlying transport

Parameters:

uri - the endpoint uri to use when connecting to the resource

timeout - the maximum time the operation should block before returning. The call should return immediately if there is data available. If no data becomes available before the timeout elapses, null will be returned

Returns:

the result of the request wrapped in a MuleMessage object. Null will be returned if no data was avaialable

Throws:

Exception - if the call to the underlying protocal cuases an exception

request

MuleMessage request(InboundEndpoint endpoint,
                    long timeout)
                    throws Exception

Make a specific request to the underlying transport

Parameters:

endpoint - the endpoint to use when connecting to the resource

timeout - the maximum time the operation should block before returning. The call should return immediately if there is data available. If no data becomes available before the timeout elapses, null will be returned

Returns:

the result of the request wrapped in a MuleMessage object. Null will be returned if no data was avaialable

Throws:

Exception - if the call to the underlying protocal cuases an exception

send

MuleMessage send(OutboundEndpoint endpoint,
                 MuleEvent event)
                 throws DispatchException

Sends an event from the endpoint to the external system

Parameters:

event - The event to send

Returns:

event the response form the external system wrapped in a MuleEvent

Throws:

DispatchException - if the event fails to be dispatched

getOutputStream

OutputStream getOutputStream(OutboundEndpoint endpoint,
                             MuleMessage message)
                             throws MuleException

Will get the output stream for this type of transport. Typically this will be called only when Streaming is being used on an outbound endpoint. If Streaming is not supported by this transport an UnsupportedOperationException is thrown. Note that the stream MUST release resources on close. For help doing so, see CallbackOutputStream.

Parameters:

endpoint - the endpoint that releates to this Dispatcher

message - the current message being processed

Returns:

the output stream to use for this request

Throws:

MuleException

getMuleContext

MuleContext getMuleContext()

getRetryPolicyTemplate

RetryPolicyTemplate getRetryPolicyTemplate()
