Detailed Description

An array of ExternalServer(s)

ExternalServerArray is an ExternalSystemArray specialized in servers' driver.

[Inherited]

ExternalSystemArray is an abstract class containing and managing external system drivers.

Also, ExternalSystemArray can access to ExternalSystemRole(s) directly. With the method, you can use an ExternalSystemRole as "logical proxy" of an ExternalSystem. Of course, the ExternalSystemRole is belonged to an ExternalSystem. However, if you access an ExternalSystemRole from an ExternalSystemArray directly, not passing by a belonged ExternalSystem, and send an Invoke message even you're not knowing which ExternalSystem is related in, the ExternalSystemRole acted a role of proxy.

It's called as "Proxy pattern". With the pattern, you can only concentrate on ExternalSystemRole itself, what to do with Invoke message, irrespective of the ExternalSystemRole is belonged to which ExternalSystem.

ExternalSystemArray::getRole("something")->sendData(invoke);

Member Function Documentation

void ExternalServerArray::start ( )

overridevirtual

Start interaction.

An abstract method starting interaction with external systems.

If external systems are servers, starts connection to them, else clients, opens a server and accepts the external systems. You can addict your own procudures of starting drivers, but if you directly override method of abstract ExternalSystemArray, be careful about virtual inheritance.

• DistributedClientArray::start() calls DistributedSystemArray::start() and ExternalClientArray:start()

Implements samchon::protocol::ExternalSystemArray.

Reimplemented in samchon::example::interaction::Chief, samchon::protocol::master::DistributedServerArrayMediator, samchon::protocol::master::ParallelServerArrayMediator, and samchon::protocol::master::DistributedServerArray.
