Class FilterByAreaGeometryRequest

java.lang.Object

com.gpudb.protocol.FilterByAreaGeometryRequest

All Implemented Interfaces:

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

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

A set of parameters for GPUdb.filterByAreaGeometry(FilterByAreaGeometryRequest).

Calculates which geospatial geometry objects from a table intersect 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.

Constructor Detail

FilterByAreaGeometryRequest

public FilterByAreaGeometryRequest()

Constructs a FilterByAreaGeometryRequest object with default parameters.

FilterByAreaGeometryRequest

public FilterByAreaGeometryRequest(String tableName,
                           String viewName,
                           String columnName,
                           List<Double> xVector,
                           List<Double> yVector,
                           Map<String,String> options)

Constructs a FilterByAreaGeometryRequest object with the specified parameters.

Parameters:

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.

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.

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

xVector - List of x coordinates of the vertices of the polygon representing the area to be filtered.

yVector - List of y coordinates of the vertices of the polygon representing the area to be filtered.

options - Optional parameters.

Method Detail

getClassSchema

public static org.apache.avro.Schema getClassSchema()

This method supports the Avro framework and is not intended to be called directly by the user.

Returns:

the schema for the class.

getTableName

Returns:

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.

setTableName

public FilterByAreaGeometryRequest setTableName(String tableName)

Parameters:

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.

Returns:

this to mimic the builder pattern.

getViewName

public String getViewName()

Returns:

If provided, then this will be the name of the view containing the results. Must not be an already existing collection, table or view.

setViewName

public FilterByAreaGeometryRequest setViewName(String viewName)

Parameters:

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.

Returns:

this to mimic the builder pattern.

getColumnName

public String getColumnName()

Returns:

Name of the geospatial geometry column to be filtered.

public FilterByAreaGeometryRequest setColumnName(String columnName)

Parameters:

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

Returns:

this to mimic the builder pattern.

getXVector

public List<Double> getXVector()

Returns:

List of x coordinates of the vertices of the polygon representing the area to be filtered.

setXVector

public FilterByAreaGeometryRequest setXVector(List<Double> xVector)

Parameters:

xVector - List of x coordinates of the vertices of the polygon representing the area to be filtered.

Returns:

this to mimic the builder pattern.

getYVector

public List<Double> getYVector()

Returns:

List of y coordinates of the vertices of the polygon representing the area to be filtered.

setYVector

public FilterByAreaGeometryRequest setYVector(List<Double> yVector)

Parameters:
