Together with the classes jade.core.Profile and jade.core.Runtime this package provides support for the JADE in-process interface that allows external Java applications to use JADE as a kind of library and to launch the JADE Runtime from within the application itself. The classes of this package wraps the main actors of the JADE platform and allows to interact with them and, in particular, to control their life-cycle. A section of the Programmer's Guide contains a detailed description of the usage of the in-process interface.
