Detects the current state of the physical connection

• Manages connection state• Fires an event when

connection state change occurs

• Has public methods to change the online/offline state









ExecutorExecutor





• Provides the base class implemented by all application-supplied Service Agents.

• Base class is responsible for registering the service agent with the service agent registry.

• Returns the results back to the appropriate Service Agents after processing

• Allows the application to request reference data to be downloaded

• Facade for the Queue Storage Providers:

• Methods for queuing and dequeuing messages.

Provides:• Ability to queue

messages• Channel for

getting results back to the application









ExecutorExecutor





• When online:• Takes messages off the

queue• Calls the Online Proxy

to send them to the remote service.

• Sends responses from the remote service back to the application.

• Provides the data store
