Galder Zamarreno commented on ISPN-244:
---------------------------------------
After further discussions, we're likely to provide this via GlobalConfiguration since
it enables the possibility of defining these via XML too, at least for external modules
such as 2nd level cache provider. For internal, a method like ISPN-245 will most likely be
used.
Enable external user/framework defined Externalizers
----------------------------------------------------
Key: ISPN-244
URL:
https://jira.jboss.org/jira/browse/ISPN-244
Project: Infinispan
Issue Type: Feature Request
Components: Marshalling
Reporter: Galder Zamarreno
Fix For: 4.1.0.BETA1
Create an internal magic number (i.e. -1 or 255) for user defined externalizers. This is
done to avoid users using our number space.
So, internally: <magic_number> <stream>
Users: <magic_number><user defined magic number (int)> <stream>
Mandate unsigned ints so that we can optimise by sending them as variable lenght
Internal frameworks could use high enough numbers for example up to 2 bytes: 5000, 7000,
20000
1 byte: 128
2 bytes: 32767
3 bytes: ...
GlobalConfiguration.registerMarshallable(Class type, Externalizer ext, int id);
Maybe CacheManager better?
CacheManager.registerMarshallable(Class type, Externalizer ext, int id);
Future improvement, maybe generate ids automatically for user defined classes?
