Detailed Description

A set of parameters for GPUdb::filterByRadiusGeometry.

Calculates which geospatial geometry objects from a table intersect 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.

Constructor & Destructor Documentation

◆ FilterByRadiusGeometryRequest() [1/2]

gpudb::FilterByRadiusGeometryRequest::FilterByRadiusGeometryRequest ()
inline

Constructs a FilterByRadiusGeometryRequest object with default parameters.

Definition at line 30 of file filter_by_radius_geometry.h.

◆ FilterByRadiusGeometryRequest() [2/2]

gpudb::FilterByRadiusGeometryRequest::FilterByRadiusGeometryRequest (const std::string &tableName_,
const std::string &viewName_,
const std::string &columnName_,
const doublexCenter_,
const doubleyCenter_,
const doubleradius_,
const std::map< std::string, std::string > &options_ )
inline

Constructs a FilterByRadiusGeometryRequest object with the specified parameters.

Parameters
[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]columnName_Name of the geospatial geometry column to be filtered.
[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]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.The default value is an empty map.
