PseudoProtocol

The aim of this project is to simulate Protocol.

The check is at runtime and not at compilation time, too bad.

Create a protocol

First we have the Protocol class. All others protocols classes must extends it.

Class extends Protocol

Then each protocol define the function and property

Class constructor
    Super()
    This.addProperty("name"; Is text)
    This.addFunction("getRepository")

Setup the protocol store

A variable ps represent the protocol store. You must instanciate it one time and fill it with all protocols.

To do so just instantiate one times them.

ps:=New object()
cs.ServiceProtocol.new() // auto register into ps
cs.MySecondProtocol.new()

then you can access protocol with ps: ps.ServiceProtocol

or use psInit which instanciate all protocols found in class store cs.

Check if instance implement the protocol

You have an instance and want to know if all properties and functions match a protocol.

$instance:=cs.Github.new()

You could ask protocol for that:

If(ps.ServiceProtocol.isInstance($instance))
    // do something
End if

You could also assert if you code need to be called by a correct instance type

If (ps.ServiceProtocol.assertedInstance($instance))
    // do something
End if 

💡 You could do ASSERT(ps.ServiceProtocol.isInstance(This)) in your class object contructor to check immediately that it follow the protocol rules

How it work?

Just by using JSON Validate with schema validation. The protocol is the schema.
