Engine

Description

An Engine is an application which

• Provides Object hosting services required by a Core
• Persistence
• Referent/Relation modeling
• Dynamic function loading

Aspects

Persistence

• Referent
  • Has only its own ID. Everything about it comes from the other three classes:
• referent property
  • Associates arbitrary static data with a Referent.
• Relation
  • Relates a subject to an object via a relationship (all three are Referents)
• Behavior
  • Associates programming with a referent

Refrent/Relation Model

Behavior

Programming Interface

engine = new Engine ...
$root = engine.root
$sys = engine.sys
assert $sys.parent is $root
SEND = engine.send

SEND $root, 'spawn'
  .then (child) ->
    assert child.parent is $root
    assert child in $root.children

$root.addProperty 'name', 'root'
$root.addMethod 'set_root_name', CoffeeScript.compile, """
    (newName) ->
      name = newName
