What is the best way to declare sorted association in grails domain classes ?
- by fabien7474
It seems that there are two different ways of declaring sorted associations in Grails :
Method 1 (see here) using default sort order
class Book {
String title
}
class Author {
static hasMany = [books : Book]
static mapping = { books sort: "title"}
}
Method 2 (see here) using SortedSet
class Book implements Comparable {
String title
int compareTo(obj) {
title <=> obj.title
}
}
class Author {
SortedSet books
static hasMany = [books : Book]
}
I am not sure which one to use and what is the difference (if any), pros and cons between using one against the other.
I would appreciate any clarification.
Thank you
