1. Brief Explanation of Variable

   1. It is generated upon reading XML script files.

   2. This class instances are included in Script::BODY 2. Other comments:

   This class will hold definitions for variables. During initialization, they only contain strings for their function definitions (self.sFunction). Later “self. fSetfFunction” will be called and Variable::_fFunction will contain a real function definition. Variable class can be called, and have caches to store any calculated values.

   I think calling a user-defined class may not be efficient in terms of computation time. We may need to think of a new way to store caches and compute quickly.

2. List of Member Variables and Methods

   0. How to Create a class instance

      >>> s=Script(sFilePath=".\\script\\Script2.txt")
      >>> v=s.BODY["aa"] 'take the Variable named "aa" as an example
      

   1. Functions

      1. __init__(self,sName=”“,sFunction=”“,sModule=”“,sProduct=”“,sAccumulation=”“)

         >>> v.__dict__
         {'sName': 'aa',
          'sFunction': 'def aa(t):\n\t\t\t\treturn t',
          'sModule': 'oneguy',
          '_fFunction': None,
          'lsFuncArgs': [],
          '_dCache': {},
          'lProduct': ['PROD1'],
          'lAccumulation': ['ACC1']}
         

      2. fSetfFunction(self,mModule_fFunc,bReInitialize=False)

         >>> import imp
         >>> module = imp.new_module("haha")
         >>> print(v._fFunction)
         None
         >>> v.fSetfFunction(module,False)
         >>> v._fFunction
         <function haha.aa(t)>
         >>> v._fFunction(23)
         23
         

      3. fReInitialize(self)

         TODO: explain this later

      … and other functions
