In the previous section, we showed the class diagram of the example we will show here. As you can see, we used a model class called Person. It is just a case class with the following definition:
case class Person(name: String, age: Int, address: String)
Since there will be different formats available in our application, we have defined a common interface that all parsers will implement:
trait Parser[T] { def parse(file: String): List[T]}
Now, let's have a look at the implementations. First is the CSVParser:
import com.github.tototoshi.csv.CSVReaderclass CSVParser extends Parser[Person] { override def parse(file: String): List[Person] = CSVReader.open(new InputStreamReader(this.getClass.getResourceAsStream(file))).all().map ...
