SCROLL Demo
===========
Models and code for the [SCROLL][roledispatch] demo application.
**1. Current state:**
You are able to define compartments, roles and play-relationships. Invoking Role-methods is done via the [Dynamic][scala-dynamic] trait.
See the referenced [SCROLL][roledispatch] project for details.
**2. Edit and run:**
2.1. Clone this repository into your workspace.
2.2. Execute SBT and run ```gen-idea``` if you are using Intellij IDE <= 13 (to config see [here][sbt-gen-idea]). This is not required anymore since Intellij 14. Just use the built-in import SBT project functionality.
2.3. Or execute SBT and run ```eclipse``` if you are using the Eclipse Scala IDE. (to config see [here][gen-eclipse])
2.4. Run it from the SBT console with ```run``` and visit ```127.0.0.1:8080``` in your browser.
**3. Example - SmartCar:**
The [example][smartcar] is based on the following models:
```scala
class SmartCarDemo {
val transportation = new Transportation {
// adding some persons with their cars
val peter = new Person("Peter")
val googleCar = new Car("A-B-C-001")
val harry = new Person("Harry")
val toyota = new Car("A-B-C-002")
// adding some locations
new Location("Munich") play new Source()
new Location("Berlin") play new Source()
new Location("Dresden") play new Target()
// and doing a manual transportation now
harry play new ManualTransport.Driver()
toyota play new ManualTransport.NormalCar()
ManualTransport partOf this
+toyota drive()
ManualTransport play new TransportationRole(one[Source]("name" ==# "Berlin"), one[Target]()) travel()
// and here a autonomous one
peter play new AutonomousTransport.Passenger()
googleCar play new AutonomousTransport.SmartCar()
AutonomousTransport partOf this
+googleCar drive()
AutonomousTransport play new TransportationRole(one[Source]("name" ==# "Munich"), one[Target]()) travel()
+peter brake()
+harry brake()
}
/**
* Defining all natural types.
*/
class Person(val name: String)
class Car(val licenseID: String)
class Location(val name: String)
/**
* Defining all contexts with it's roles.
*/
class Charging() extends Compartment {
class ChargingStation() {
def doCharge() {
info("Charging ...")
}
}
class ChargingCar() {
def drive() {
info("I can't drive while charging!")
}
}
}
class Transportation() extends Compartment {
object AutonomousTransport extends Compartment {
class SmartCar() {
def drive() {
info("I am driving autonomously!")
}
}
class Passenger() {
def brake() {
val name: String = (+this).name
info(s"I can't reach the brake. I am $name and just a passenger!")
}
}
}
object ManualTransport extends Compartment {
class NormalCar() {
def drive() {
val driver = one[Driver]()
info("I am driving with a driver called " + (+driver).name + ".")
}
}
class Driver() {
def brake() {
val name: String = (+this).name
info(s"I am $name and I am hitting the brakes now!")
}
}
}
class TransportationRole(source: Source, target: Target) {
def travel() {
val from: String = (+source).name
val to: String = (+target).name
val license: String = one[Car]().licenseID
val kindOfTransport = getCoreFor(this) match {
case ManualTransport => "manual"
case AutonomousTransport => "autonomous"
}
info(s"Doing a $kindOfTransport transportation with the car $license from $from to $to.")
}
}
class Target()
class Source()
}
}
```
Running it produces the following output:
```
I am driving with a driver called Harry.
Doing a manual transportation with the car A-B-C-002 from Berlin to Dresden.
I am driving autonomously!
Doing a autonomous transportation with the car A-B-C-001 from Munich to Dresden.
I can't reach the brake. I am Peter and just a passenger!
I am Harry and I am hitting the brakes now!
