GetData multiple times

    If you call GetData multiple times from the same location from different functions will you get the same data?

    Does calling GetData clear out what is in that memory location?

    example:

    def Message(self, op, type, data) : #op is the tag
          if type==c4d.MSG_DESCRIPTION_POSTSETPARAMETER:
              startJoint = d.GetData(FINAL_LINK)

    def Execute(self, tag, doc, op, bt, priority, flags) :
          self.final_cd = data.GetData(FINAL_LINK)

    do startJoint and self.final_cd have the same data?

    Look at the documentation of BaseContainer::GetData(). You can also easily verify this with
    a short example.

    But to answer your question, not it does not clear the data. GetData() would be a very inappropriate
    name if it would. They will get the same data unless something else was able to access and modify
    the specified entry.

    We assume, of course, that "d" in Message() and "data" in Execute() refer to the same object.
