Usage

import net.kemitix.properties.typed.TypedProperties;
import net.kemitix.properties.typed.TypedProperty;

class Usage {
  public static void main(String[] args){
    // Create a new instance
    TypedProperties properties = TypedProperties.create();

    // Set a value - creates a new instance - immutability
    // parameters: key, value
    // - key is a class/interface, that extends TypedProperty<T>,
    //   where T is the type of the value.
    // - value is of type T
    TypedProperties updated = properties.with(Name.class, "Name");

    // Retrieve a value
    // parameters: key, value-type
    // - key is same as above
    // - value-type is the type of the value - must match key
    Optional<String> result = updated.find(Name.class, String.class);
  }
}
public interface Name
  extends TypedProperty<String> {}
