cmion.storage.BlackBoard

public class BlackBoard
extends CmionStorageContainer

The BlackBoard is a storage container for competencies to share information with each other. For time critical applications, it has some additional functions to store "real-time" properties, those are properties that are not written and read through ION requests and events but directly. The advantage of this is faster reaction times (not tied to the ION simulation loop), the disadvantage, is that there are no event listeners for changes to those properties available and access is less controlled
