Hi,
Re: https://jira.jboss.org/jira/browse/ISPN-125
I've been thinking more about this and I don't have the reading part
very clear. At runtime, it's very easy to check the externalizer map to
see if there's externalizer for class A and if there isn't any, inspect
the class for @Marshallable annotation, instantiate the A's Externalizer
class and add it to the map.
However, the reading part is a fairly difficult problem to crack cos all
you'd get would be an Id which you'd need to map back to an Externalizer
that will be used for reading. However, how does the reader know what's
the mapping Id to Externalizer mapping?
Crazy idea from Ignoramus Park here, but how about storing the Externalizer
class in the cache itself? Then if an endpoint gets an ID it doesn't know,
it can hit the cache to ask for it.
