Detailed Description
Auto-updating DMR user database.
This class represents the complete DMR user database. The user database gets downloaded from https://www.radioid.net/static/users.json and kept up-to-date by re-downloading it periodically (by default every 30 days). This user database gets used in the GUI application to help assemble private call contacts and to assemble so-called CSV callsign databases, that are programmable to some DMR radios to resolve the DMR ID to callsigns and names.
Constructor & Destructor Documentation
◆ UserDatabase()
|
explicit |
Constructs the user-database.
The constructor will download the current user database if it was not downloaded yet or if the downloaded version is older than updatePeriodDays days.
The documentation for this class was generated from the following files:
