DtNavAreaQuery Class Reference

Base class for all asynchronous Nav Area queries. In this context asynchronous means non-blocking. The queries may be performed in this thread or another thread, depending on configuration, but the result will take some time to complete. The calling function must call the complete() method to determine when the query has finished.
