C++ Reference: class Demon
Note: This documentation is automatically generated.
A Demon is the base element of a propagation queue. It is the main
object responsible for implementing the actual propagation
of the constraint and pruning the inconsistent values in the domains
of the variables. The main concept is that demons are listeners that are
attached to the variables and listen to their modifications.
There are two methods:
- Run() is the actual method called when the demon is processed.
- priority() returns its priority. Standard priorities are slow, normal
or fast. "immediate" is reserved for variables and is treated separately.
This method returns the priority of the demon. Usually a demon is
fast, slow or normal. Immediate demons are reserved for internal
use to maintain variables.

They manage constraint propagation and inconsistent value pruning. Key actions include: `Run()`, the primary processing method; and `priority()`, which determines execution order (slow, normal, fast). `inhibit()` pauses a demon, while `desinhibit()` reactivates it. `DebugString` is also a method to get a string of the demon. Immediate priority is exclusively for variables.\n"]]
