API: How can I make a transform?

(Referenced from 'Complete Maya Programming') Waaaay exciting!
It should be noted that any time you use API calls outside of a plugin to modify the DG, you can't undo the operation.

# Python code
import maya.OpenMaya as om

# optionA:
transFn = om.MFnTransform()
transObj = transFn.create()
name = transFn.name()

# optionB:
transFn = om.MFnTransform()
transObj = transFn.create()
# Illustrating inheritance: 
dagFn = om.MFnDagNode(transObj)
name = dagFn.name()

print name
# transform1

Class hierarchy:

• MFnBase
  • MFnDependencyNode
    • MFnDagNode
      • MFnTransform
