Details - I suggest to introduce a method geometryType() in entity for
the following reasons:
1)Currently one has to use entity.geometry().type() to get the
of an entity. This seems to be a very costly way e.g. in ALUGRID. I
ALUGRID constructs Geometry objects when geometry() is called and
everytime the GeometryType of an entity is needed.
2)This problem occurs everytime you want to write portable code for
grids which could have different element types. E.g. the mcmgmapper
works this way.
3)The GeometryType is primary a property of the entity and not only of
This is obvious since you need (GeometryType,level, levelindex) or
to fully qualify an entity.
4)The method is easy to implement, since grids with only one type now
it apriory and
grids with multiple types could just forward geometry().type() if
there is no better way.
