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 geospatial geometry column.

viewName - If provided, then this will be the name of the view containing the results. Has the same naming restrictions as tables. The default value is ''.

columnName - Name of the column to be used in the filter. Must be a geospatial geometry column.

inputWkt - A geometry in WKT format that will be used to filter the objects in tableName. The default value is ''.

operation - The geometric filtering operation to perform Supported values:

• CONTAINS: Matches records that contain the given WKT in inputWkt, i.e. the given WKT is within the bounds of a record's geometry.
• CROSSES: Matches records that cross the given WKT.
• DISJOINT: Matches records that are disjoint from the given WKT.
• EQUALS: Matches records that are the same as the given WKT.
• INTERSECTS: Matches records that intersect the given WKT.
• OVERLAPS: Matches records that overlap the given WKT.
• TOUCHES: Matches records that touch the given WKT.
• WITHIN: Matches records that are within the given WKT.

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.
