MapSettingsManager is a centralized object for management (creating,
|
|
loading, storing, saving, etc.) of config settings related to the Map.
|
|
|
|
It has two phases: the initial r/w "gather and modify settings" state, and
|
|
the final r/o "read and save settings" state.
|
|
|
|
The typical use case is, in order, as follows:
|
|
- Create a MapSettingsManager object
|
|
- Try to load map metadata into it from the metadata file
|
|
- Manually view and modify the current configuration as desired through a
|
|
Settings-like interface
|
|
- When all modifications are finished, create a 'Parameters' object
|
|
containing the finalized, active parameters. This could be passed along
|
|
to whichever Map-related objects that may require it.
|
|
- Save these active settings to the metadata file when requested
