Agency manages Critics. Since classes are not really first class objects in java, a singleton instance of Agency is made and passed around as needed. The Agency keeps a registry of all Critics that should be applied to each type of design material. When a design material instance is critiqued it asks Agency to apply all registered Critic's. In the current scheme there is a thread that proactively, continuously critiques the Design at hand, even if the user is idle! This is simple and it works. The disadvantage is that _all_ active critics related to a given design material are applied, regardless of the reason for the critiquing and a lot of CPU time is basically wasted.
TODO: I am moving toward a more reactionary scheme in which specific design manipulations in the editor cause critics relevant to those manipulations to be applied. This transition is still half done. Trigger's are the critiquing requests. The code for triggers is currently dormant (latent?).

theAgency()
Since Java does not really suport classes as first class objects, there is one instance of Agency that is passed around as needed. theAgency is actually stored in Designer.theDesigner(). |
