Serializable alternative to MultiHashMap
Hi,
I have been using MultiHashMap and according to documentation
this objects has been set as deprecated and it is recomended that we use
MultiValueMap however MultiValueMap is not serializable.
Is there any serializable alternative to MultiValueMap ?
Case not, why do you decided to deprecate MultiHashMap before
providing a Serializable alternative ?
Is it expected MultiValueMap to be serializable in the near
future ?
Regards,
Adelino.

Please open a JIRA issue about this! I am sure it will be handled for the
next release then.

There is nothing wrong with
ArrayList<ArrayList<OMElement>>
You only need to write the correct code for adding and lookup. Often
things like this are used:
Map<String, ArrayList<OMElement>>
With code like:
if (!map.containsKey(s)) map.put(s, new ArrayList<OMElement>());
map.get(s).add(ome);

i had a requirement which called for accumulating a collection of known objects
so i used parameterised ArrayList e.g.
ArrayList<OMElement>
I have yet to discover any package which will support Collection(s) of Collection(s)
anyone ?
