Sorted list
Hi everyone,
I've been trying to find a way to have a sorted list where I can do a
get method on the key, right now I'm using to lists, one that I have
implemented based on the java SortedMap list and a vector, then when OJB
uses the setList method I go and add all the elements to the sorted map,
and viceversa.... Problem is of course performance.... I've been looking
in implementing my Sorted List by implementing the ManageableCollection
Interface, the question Is if that's all I would need to do? Just
implement those methods and have my repository collection tag to my own
?
Anyone has come across this before? Any hints appreciated
Thanks,

Ok I'll try that way

For sure, I'll let you know when I'm done and tested the solution

yes, that should be sufficient. have a look at
org.apache.ojb.broker.util.collections.ManageableHashSet for an example.
It is a HashSet that implements the ManageableCollection interface.
Are you willing to share your Map class? I'd love to add more user
defined ManageableCollections to the util.collections package.
cheers,
