maxBy

For any types T and K,

maxBy(collection: Bag<T>,  keySelector: T -> K) : T?

Gets the greatest item in the collection, where items are ordered by the value returned by applying keySelector to the item.

• For example, if the following function has been declared getRoutePrefix(route) = route.prefix;, and if routes is a variable referring to some list of IpEntry records, then maxBy(routes, getRoutePrefix) evaluates to the route with the largest prefix (aka subnet). See how comparisons work for more on how subnets are ordered.
• Similar to max and min, this function returns null if there are no items in the collection.
• Note that this method accepts both Lists and Bags ─since Lists subtype Bags
