Hi, You found a use case for in-memory H2GIS layer that Michaël was dreaming about a few days ago. Then you could use SQL somehowl like “SELECT DISTINCT geometry_type(the_geom)…”
Meanwhile you could study what Edit – Extract – Extract layers by geometry type does. Now it already sends a message if there is nothing to split, perhaps you could modify it to tell if there IS something to split, but disable the creation of new layers. -Jukka Rahkonen- Lähettäjä: Giuseppe Aruta [mailto:giuseppe.ar...@gmail.com] Lähetetty: 30. joulukuuta 2015 20:57 Vastaanottaja: OpenJump develop and use Aihe: Re: [JPP-Devel] Check if a Geometry collection (or a Feature Schema) is made by a single geometry type Thanks for the answers. I want to develop a way to check if a selected vector layer has different geometries or if it is if one geometry type. I checked on OJ code but I didn' t find what I needed. I will study an alternative way.
