Detailed Description

A set of input parameters for const.

Calculates which objects from a table are within a named area of interest (NAI/polygon). The operation is synchronous, meaning that a response will not be returned 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.

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). If filtering a collection, all child tables where the filter expression is valid will be filtered; the filtered result tables will then be placed in a collection specified by viewName.
[in]	viewName_	If provided, then this will be the name of the view containing the results. Has the same naming restrictions as tables.
[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. gpudb::filter_by_area_collection_name: Name of a collection which is to contain the newly created view. If the collection provided is non-existent, the collection will be automatically created. If empty, then the newly created view will be top-level.
