de.tuclausthal.informatik.winf.mobileagents.packaging.Packager
A packager is responsible for translating an agent into binary format, so that it can be send to another host. Depending on the packager, code and data can be migrated or only a specific data instance. It is even possible to refine the packager to ask the other host, if some files are already present and do not send them. The packager only provides two methods: One for converting the agent into a byte-stream and another for reconstructing the agent from a byte-stream. @author dluebke @version 1.0.2 (2003-09-23) @since 1.0
