Method non_empty_domain_var

tiledb/sm/cpp_api/array.h:909–936

* Retrieves the non-empty domain from the array on the given dimension. * This is the union of the non-empty domains of the array fragments. * Applicable only to var-sized dimensions. * * **Example:** * @code{.cpp} * tiledb::Context ctx; * tiledb::Array array(ctx, "s3://bucket-name/array-name", TILEDB_READ); * // Specify the dimension type (example uint32_t) * auto non_e

   *         on the input dimension.
