The guava-libraries have a class Ordering. I’m wondering if it’s thread safe.
For example, can it be used as a static variable?
public static Ordering<String> BY_LENGTH_ORDERING = new Ordering<String>() {
public int compare(String left, String right) {
return Ints.compare(left.length(), right.length());
}
};
It’s as thread-safe as your
comparemethod.Default implementation of Ordering does not have any instance data, so the only thing that matters is how you define your compare method.
