Demon (com.google.ortools:ortools-java 9.8.3296 API)

java.lang.Object
- com.google.ortools.constraintsolver.BaseObject
- - com.google.ortools.constraintsolver.Demon

```
public class Demon
extends BaseObject
```
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.

```
public void delete()
```
    Overrides:
    
    delete in class BaseObject
  - run
```
public void run(Solver s)
```
    This is the main callback of the demon.
  - priority
```
public int priority()
```
    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.
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class BaseObject
  - inhibit
```
public void inhibit(Solver s)
```
    This method inhibits the demon in the search tree below the
    current position.
  - desinhibit
```
public void desinhibit(Solver s)
```
    This method un-inhibits the demon that was previously inhibited.
