Method Query

tiledb/sm/cpp_api/query.h:135–143

* Creates a TileDB query object. * * The query type (read or write) must be the same as the type used to open * the array object. * * The storage manager also acquires a **shared lock** on the array. This * means multiple read and write queries to the same array can be made * concurrently (in TileDB, only consolidation requires an exclusive lock for * a short period of time

   * @param type The TileDB query type
