Hi,
I remember we had this discussion at one point, sorry if I am repeating it.
ConstantObjectTable has all the externalizer's statically defined within it. Can it
just read them on the fly from the annotations existing on the object it needs to
serialize? I.e. if e.g. TransientMortalCacheEntry is annotated as @Marshallable why is it
needed to add it to the ConstantObjectTable again?
There primary reason is: How is a node that hasn't serialized
TransientMortalCacheEntry gonna know that what comes through the wire is a
TransientMortalCacheEntry? It needs to know for a given ID, which externalizer to use to
read. So, we either, did this statically or via annotation scanning of classpath. The
latter is no no, so we went for static. Once we saw we needed static definition, we
decided to do it both ways, for given a Class, give me the Externalizer (writing) and for
a given ID, give me the Externalizer (reading)
Cheers,
Mircea
