| # Power framework in depth |
| |
| This section focuses on how power framework works conceptually. This information |
| equips you to arbitrarily extend the power topology into your code rather than |
| simply connecting to the part of the topology exposed by System Activity |
| Governor. |
| |
| |
| ## Overview |
| |
| Power framework uses a directed, acyclic graph ("DAG") of power dependencies to |
| manage the system. Power framework does not know the DAG for a particular |
| system, but relies on components in the system to build the DAG. All operations |
| that power framework performs are walks of the DAG with different visit order |
| (ie. pre-, post-, in-) and consequences. **That's basically it, you now |
| understand the power framework, the rest is implementation details, albeit |
| important ones.** |
