org.openbp.server.context.TokenContext
The context for process execution. The token context contains all information that reflects the current state of the process. This includes process execution data, the current global and socket parameter values of the process, i/o etc. The TokenContext interface now extends the RuntimeAttribute interface. This provides the ability to store arbitrary objects in a map. However, the map won't be serialized to persistent storage. When a context is executed by the engine, the thread executing the context is saved as runtime attribute under the key {@link TokenContext#RUNTIME_ATTRIBUTE_THREAD}. This feature may be used to terminate hanging threads by force in emergency situations. @author Heiko Erhardt
