Detailed Description

An external server driver.

The ExternalServer is an abstract class, derived from the ExternalSystem class, connecting to remote, external server. Extends this ExternalServer class and overrides the createServerConnector() method following which protocol the external server uses.

[Inherited] ExternalSystem}

An external system driver.

The ExternalSystem class represents an external system, connected and interact with this system. ExternalSystem takes full charge of network communication with the remote, external system have connected. Replied Invoke messages from the external system is shifted to and processed in, children elements of this class, ExternalSystemRole objects.

Bridge & Proxy Pattern

The ExternalSystem class can be a bridge for logical proxy. In framework within user, which external system is connected with this system, it's not important. Only interested in user's perspective is which can be done.

By using the logical proxy, user dont't need to know which role is belonged to which system. Just access to a role directly from ExternalSystemArray.getRole. Sends and receives Invoke message via the role.

ExternalSystemRole can be accessed from ExternalSystemArray directly, without inteferring from ExternalSystem, with ExternalSystemArray.getRole.
When you want to send an Invoke message to the belonged system, just call ExternalSystemRole.sendData(). Then, the message will be sent to the external system.
Those strategy is called Bridge Pattern and Proxy Pattern.
