Detailed Description

A set of input parameters for filterByArea(const FilterByAreaRequest&) const.

Calculates which objects from a table are within a named area of interest (NAI/polygon). The operation is synchronous meaning that GPUdb will not return the request until all the matching objects are fully available. The response payload provides the count of the resulting set. A new resultant set (view) which satisfies the input NAI restriction specification is created with the name viewName passed in as part of the input.

Definition at line 31 of file filter_by_area.h.

gpudb::FilterByAreaRequest::FilterByAreaRequest ( const std::string &  tableName, const std::string &  viewName, const std::string &  xColumnName, const std::vector< double > &  xVector, const std::string &  yColumnName, const std::vector< double > &  yVector, const std::map< std::string, std::string > &  options  )

inline

Constructs a FilterByAreaRequest object with the specified parameters.

Parameters

[in]	tableName	Name of the table to filter. This may be the name of a collection, a table or a view (when chaining queries). Collections may be filtered only if all tables within the collection have the same type ID.
[in]	viewName	If provided, then this will be the name of the view containing the results. Must not be an already existing collection, table or view. Default value is an empty string.
[in]	xColumnName	Name of the column containing the x values to be filtered.
[in]	xVector	List of x coordinates of the vertices of the polygon representing the area to be filtered.
[in]	yColumnName	Name of the column containing the y values to be filtered.
[in]	yVector	List of y coordinates of the vertices of the polygon representing the area to be filtered.
[in]	options	Optional parameters. Default value is an empty std::map.
