Class SpatialTypeFunctions

java.lang.Object

org.apache.calcite.runtime.SpatialTypeFunctions

public class SpatialTypeFunctions
extends Object

Helper methods to implement spatial type (ST) functions in generated code.

Remaining tasks:

• Determine type code for ExtraSqlTypes.GEOMETRY
• Should we create aliases for functions in upper-case? Without ST_ prefix?
• Consider adding spatial literals, e.g. `GEOMETRY 'POINT (30 10)'`
• Integer arguments, e.g. SELECT ST_MakePoint(1, 2, 1.5), ST_MakePoint(1, 2)
• Are GEOMETRY values comparable? If so add ORDER BY test
• We have to add 'Z' to create 3D objects. This is inconsistent with PostGIS. Who is right? At least document the difference.
• Should add GeometryEngine.intersects; similar to disjoint etc.
• Make ST_MakeLine(Geometry, Geometry) varargs
