SegmentDataLoader class abstract
Provides the abstract class for the access to the segments data available in the local OCM map.
Please be aware that the methods within this class load map data synchronously. In the event of absent data in the disk cache, the data will be retrieved from the remote server. To mitigate the potential freezing of the calling thread, it is advisable to proactively prefetch map data around the working area.
Note: This is a beta release of this feature, so there could be a few bugs and unexpected behaviors. Related APIs may change for new releases without a deprecation process.
