Method Detail

configureDispatcherPool

protected void configureDispatcherPool()

Overrides:

configureDispatcherPool in class AbstractConnector

setMaxDispatchersActive

public void setMaxDispatchersActive(int value)

Description copied from class: AbstractConnector

Configures the maximum number of dispatchers that can be concurrently active per endpoint

Overrides:

setMaxDispatchersActive in class AbstractConnector

Parameters:

value - max. number of active dispatchers

getReceiverKey

protected Object getReceiverKey(Service service,
                                InboundEndpoint endpoint)

Description copied from class: AbstractConnector

The method determines the key used to store the receiver against.

Overrides:

getReceiverKey in class AbstractConnector

Parameters:

service - the service for which the endpoint is being registered

endpoint - the endpoint being registered for the service

Returns:

the key to store the newly created receiver against

createReceiver

public MessageReceiver createReceiver(Service service,
                                      InboundEndpoint endpoint)

• filterPatterns
• filterClass
• pollingFrequency

Overrides:

createReceiver in class AbstractConnector

Parameters:

endpoint - the endpoint that defies this inbound communication

Returns:

an instance of the message receiver defined in this connectors' TransportServiceDescriptor initialised using the service and endpoint.

Throws:

Exception - if there is a problem creating the receiver. This exception really depends on the underlying transport, thus any exception could be thrown
