lwtype_is_collection()

int lwtype_is_collection

(

uint8_t

type

)

Return TRUE if the geometry is structured as a wrapper on a geoms/ngeoms list of sub-geometries.

Determine whether a type number is a collection or not.

Use lwgeom_is_unitary to determine if the numgeometries/geometryn accessor pattery makes sense
