A network driver for a distributed client.
DistributedClient is an DistributedSystem specialized in client driver.
DistributedSystem class is an ExternalSystem having role as DistributedSystemRole objects with performance index and history log allocation of DistributedSystemRole objects and have requsted Invoke message to related external system.
The greatest difference between DistributedSystem and ExternalSystem is, unlike the ExternalSystem class which having is ExternalSystemRole objects exclusively, DistributedSystem does not monopoly a DistributedSystemRole. The DistributedSystemRole can allocatedto multiple DistributedSystem.
DistributedSystem and DistributedSystemRole classes have performance index and history log archiving what they've requested to the related distributed system. Allocating DistributedSystemRole objects to DistributedSyste will be determined those performance index and history log for optimize distribution of elasped time about each Invoke message processing.
ExternalSystem is a boundary class interacting with an external system by network communication. Also, ExternalSystem is an abstract class that a network role, which one is server and which one is client, is not determined yet.
The ExternalSystem has ExternalSystemRole(s) groupped methods, handling Invoke message interacting with the external system, by subject or unit of a moudle. The ExternalSystemRole is categorized in a 'control'.
The ExternalSystem class takes a role of interaction with external system in network level. However, within a framework of Samchon Framework, a boundary class like the ExternalSystem is not such important. You can find some evidence in a relationship between ExternalSystemArray, ExternalSystem and ExternalSystemRole.
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, it's called "Proxy pattern".
Like the explanation of "Proxy pattern", you can utilize an ExternalSystemRole as a proxy of an ExternalSystem. 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.
