[infinispan-issues] [JBoss JIRA] Work started: (ISPN-244) Enable external user/framework defined Externalizers

Enable external user/framework defined Externalizers ---------------------------------------------------- Key: ISPN-244 URL: https://jira.jboss.org/browse/ISPN-244 Project: Infinispan Issue Type: Feature Request Components: Marshalling Reporter: Galder Zamarreño Assignee: Galder Zamarreño Labels: hackathon Fix For: 5.0.0.ALPHA1, 5.0.0.Final 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?
