Persistence
Jetfire
objects and classes(code) are automatically serialized and stored in a
workspace or
namespace directory structure on the
Server Nexus when they are created or change. Persistence is a
first class attribute within Jetfire that is transparently applied to objects and code.
The server physical storage mechanism is typically a database or file system. Jetfire objects, including the state of executing programs, are persistent until they are deleted (and dereferenced), which may be from days to months, surviving computer shutdowns and even crashes.
Objects and classes are automatically restored when a
client nexus is created. Objects in the client nexus can be restored in a
system prevalence manner or may be selectively restored by placing objects in a non-cached
workspace and searching the server nexus.
