Class FilterByRadiusGeometryRequest

java.lang.Object

com.gpudb.protocol.FilterByRadiusGeometryRequest

All Implemented Interfaces:

org.apache.avro.generic.GenericContainer, org.apache.avro.generic.IndexedRecord

public class FilterByRadiusGeometryRequest
extends Object
implements org.apache.avro.generic.IndexedRecord

A set of parameters for GPUdb.filterByRadiusGeometry(FilterByRadiusGeometryRequest).

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 Detail

FilterByRadiusGeometryRequest

public FilterByRadiusGeometryRequest()

Constructs a FilterByRadiusGeometryRequest object with default parameters.

FilterByRadiusGeometryRequest

public FilterByRadiusGeometryRequest(String tableName,
                                     String viewName,
                                     String columnName,
                                     double xCenter,
                                     double yCenter,
                                     double radius,
                                     Map<String,String> options)

Constructs a FilterByRadiusGeometryRequest object with the specified parameters.

Parameters:

tableName - Name of the table on which the filter by radius operation will be performed. Must be an existing table.

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. The default value is ''.

columnName - Name of the geospatial geometry column to be filtered.

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.

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.

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.

options - Optional parameters.

• 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.

The default value is an empty Map.
