/**
 * This annotation is used by the Xtend compiler.
 * It turns an annotated class into an immutable value object.
 * 
 * All fields become final and a getter method is added.
 * The fields' name are prepended with an underscore (i.e. myField becomes _myField)
 * One constructor for initializing the uninitialized fields is added.
 * {@link Object#equals(Object)} and {@link Object#hashCode()} implementations are added.
 * {@link Object#toString()} implementation is added.
