Defining a service

In HexArc, the definition of a service consists in the configuration of the service and its components.

The tools for defining a service are provided by the VertxDSL. The way this DSL allows the user to define a service is best seen in the code below.

Example

import io.github.jahrim.hexarc.architecture.vertx.core.dsl.VertxDSL.*
import ColoredLampService.*

/** Service definition. */
def myColoredLampService: DeploymentGroup ?=> Service =
  new Service:                              // a new service
    name = "ColoredLampService"             // named "ColoredLampService" (for logging)

    val lampModel = ColoredLampModel()
    new Port[LampSwitchPort]:               // with a new use-case of type [LampSwitchPort]
      name = "SwitchPort"                     // named "SwitchPort"
      model = lampModel                       // implemented by <lampModel>
        
      new Adapter(LampSwitchHttpAdapter()):   // exposed by a new adapter <LampSwitchHttpAdapter>
        name = "Http"                           // named "Http"
      new Adapter(LampSwitchMqttAdapter()):   // also, by a new adapter <LampSwitchMqttAdapter>
        name = "Mqtt"                           // named "Mqtt"
        
    new Port[LampColorPort]:                // also, with a new use-case of type [LampColorPort]
      name = "ColorPort"                      // named "SwitchPort"
      model = lampModel                       // implemented by <lampModel>
        
      new Adapter(LampColorHttpAdapter()):    // exposed by a new adapter <LampColorHttpAdapter>
        name = "Http"                           // named "Http"
      new Adapter(LampColorMqttAdapter()):    // also, by a new adapter <LampSwitchMqttAdapter>
        name = "Mqtt"                           // named "Mqtt"
