Module Types

The Blender.Types submodule

This module is a dictionary of Blender Python types, for type checking.

 import Blender
 from Blender import Types, Object, NMesh, Camera, Lamp
 #
 objs = Object.Get() # a list of all objects in the current scene
 for o in objs:
   print
   print o, type(o)
   data = o.getData()
   print type(data)
   if type(data) == Types.NMeshType:
     if len(data.verts):
       print "its vertices are obviously of type:", type(data.verts[0])
     print "and its faces:", Types.NMFaceType
   elif type(data) == Types.CameraType:
     print "It's a Camera."
   elif type(data) == Types.LampType:
     print "Let there be light!"

Since Blender 2.48a you can get the size of the underlying DNA structs for a collection of Blender Python types.

 # loop over Types dictionary and print the struct sizes
 # -1 where the type is not supported byt the CSizeof function
 import Blender.Types as bt
 x = dir(bt)
 for t in x:
   s = 'bt.CSizeof(bt.' + t + ')'
   print t,"=", eval(s)
