◆ filterByRadius() [1/4]
| FilterByRadiusResponse gpudb::GPUdb::filterByRadius | ( | const FilterByRadiusRequest & | request_ | ) | const |
Calculates which objects from a table lie within a circle with the given radius and center point (i.e. circular NAI).
The operation is synchronous, meaning that a response will not be returned until all the objects are fully available. The response payload provides the count of the resulting set. A new resultant set (view) which satisfies the input circular NAI restriction specification is also created if a viewName is passed in as part of the request.
For track data, all track points that lie within the circle plus one point on either side of the circle (if the track goes beyond the circle) will be included in the result.
| [in] | request_ | Request object containing the parameters for the operation. |

| [in] | tableName | Name of the table on which the filter by radius operation will be performed, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table. |
| [in] | viewName | If provided, then this will be the name of the view containing the results, in [schema_name.]view_name format, using standard name resolution rules and meeting table naming criteria. Must not be an already existing table or view. The default value is ”. |
| [in] | xColumnName | Name of the column to be used for the x-coordinate (the longitude) of the center. |
| [in] | xCenter | Value of the longitude of the center. Must be within [-180.0, 180.0]. The minimum allowed value is -180. The maximum allowed value is 180. |
| [in] | yColumnName | Name of the column to be used for the y-coordinate-the latitude-of the center. |
| [in] | yCenter | Value of the latitude of the center. Must be within [-90.0, 90.0]. The minimum allowed value is -90. The maximum allowed value is 90. |
| [in] | radius | The radius of the circle within which the search will be performed. Must be a non-zero positive value. It is in meters; so, for example, a value of ‘42000’ means 42 km. The minimum allowed value is 0. The maximum allowed value is MAX_INT. |
| [in] | options | Optional parameters.
