Constructor Detail

FilterByGeometryRequest

public FilterByGeometryRequest()

Constructs a FilterByGeometryRequest object with default parameters.

FilterByGeometryRequest

public FilterByGeometryRequest(String tableName,
                               String viewName,
                               String columnName,
                               String inputWkt,
                               String operation,
                               Map<String,String> options)

Constructs a FilterByGeometryRequest object with the specified parameters.

Parameters:

tableName - Name of the table on which the filter by geometry will be performed. Must be an existing table, collection or view containing a column named WKT.

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 column to be used in the filter. Must be 'WKT'

inputWkt - A geometry in WKT format that will be used to filter the objects in tableName.

operation - The geometric filtering operation to perform Values: contains, crosses, disjoint, equals, intersects, overlaps, touches, within.

options - Optional parameters.
