Detailed Description

template<class System = ExternalServer>
class samchon::templates::external::ExternalServerArray< System >

An array and manager of external servers.

The ExternalServerArray is an abstract class, derived from the ExternalSystemArray class, connecting to external servers.

Extends this ExternalServerArray and overrides createChild() method creating child IExternalServer object. After the extending and overriding, construct children IExternalServer objects and call the connect() method.

[Inherited] ExternalSystemArray}

An array and manager of external system drivers.

The ExternalSystemArray is an abstract class containing and managing external system drivers, ExternalSystem objects. Within framewokr of network, ExternalSystemArray represents your system and children ExternalSystem objects represent remote, external systems connected with your system. With this ExternalSystemArray, you can manage multiple external systems as a group.

You can specify this ExternalSystemArray class to be a server accepting external clients or a client connecting to external servers. Even both of them is also possible.

ExternalClientArray: A server accepting external clients.
ExternalServerArray: A client connecting to external servers.
ExternalServerClientArray: Both of them. Accepts external clients and connects to external servers at the same time.

Proxy Pattern

The ExternalSystemArray class can use Proxy Pattern. 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 Proxy Pattern.
