Assignment 2

Get started

• Install BndTools
• Import all projects starting with no.tdt4250.conversion into the eclipse workspace

Structure

• no.tdt4250.conversion.api: defines the API for all other components / projects
• no.tdt4250.conversion.converter: contains the used converter for converting the values (TransientConverter, which can convert value transiently)
• no.tdt4250.conversion.gogo: the service for commands for gogo console
• no.tdt4250.conversion.servlet: the service to start a servlet for humand readble output of the conversion
• no.tdt4250.conversion.temperature: contains basic temperature conversions
• no.tdt4250.conversion.rest: the rest service for converting values

API

Start project no.tdt.4250.conversion.rest Make an http GET-request to localhost:8080 with parameters:

• value (Double): the value that should be converted
• from (String): the unit of value
• to (String): the unit of the target converted value

For example: localhost:8080/convert?from=Fahrenheit&to=Kelvin&value=20 returns following:

{
    "success": true,
    "value": 20,
    "converted": 266.4833333333333,
    "unitFrom": {
        "name": "Fahrenheit",
        "symbol": "°F"
    },
    "unitTo": {
        "name": "Kelvin",
        "symbol": "K"
    }
}

Gogo Console

Commands:

• list: lists all available direct conversions
• add: add a new conversion e.g.: add "Centimeter(cm) = Inch(in) * 0.393 + 0"

Assignment 3

Model

I simplified the model to the relevant data for Assignment 3

Transformation

The model is transformated to .html wih Acceleo M2T. The package no.tdt4250.model.html.main contains the transformation. The output for the instance no.tdt4250.model/model/programmes.xmi is here It was generated by the Acceleo Java Standalone.

Running the transformation

• Install the Eclipse Acceleo Plugin
• Run the generateHTML.mtl file as Acceleo Programm in no.tdt4250.model.html.main.
  • specify the the instance with no.tdt4250.model/model/programmes.xmi and your desired target directory
