Get the mapping of virtual electricity flows to functionalities.
Some rules are applied to expand the virtual flows using the concrete flows available.
The factor tells how each energy value coming from a functionality
must be added with values from other functionality to compute the
energy of the virtual flow. Factors are usually 1 or -1.
The code property gives the result which may be partial:
- If all flows are available,
200000is returned. - If no flows are available (indicating that the place has no
electricity functionality or that no functionality has been attached
to a flow), the
codeis200001. Themissingproperty contains all the requested flows. - If some flows are missing, the
codeis200002and themissingproperty lists them.
