An object representation of the YAML configuration file. Extend this with your own configuration properties, and they'll be parsed from the YAML file as well.

For example, given a YAML file with this:
name: "Random Person"
age: 43
# ... etc ...
And a configuration like this:
public class ExampleConfiguration extends Configuration {
    \@NotNull
    private String name;
    \@Min(1)
    \@Max(120)
    private int age;
    \@JsonProperty
    public String getName() {
        return name;
    }
    \@JsonProperty
    public void setName(String name) {
        this.name = name;
    }
    \@JsonProperty
    public int getAge() {
        return age;
    }
    \@JsonProperty
    public void setAge(int age) {
        this.age = age;
    }
}

Dropwizard will parse the given YAML file and provide an ExampleConfiguration instance to your application whose getName() method will return "Random Person" and whose getAge() method will return 43.
