The list type UpdateType is mapped to python.

The integrated conversion can map the C++ UpdateType type to and from a String. The string has to be a list separated by ';' if it should be a combination of update types.

core.objectUpdated(5,"Selection;Geometry")

Update types implemented in Core are:

All
Visibility
Geometry
Topology
Selection
VertexSelection
EdgeSelection
HalfedgeSelection
FaceSelection
KnotSelection
Color
Texture
State

Other plugins might have implemented additional update types, which will be automatically mapped.
