Method load

libpgm/nodedata.py:48–95

Load node data from an input file located at *path*. Input file must be a plaintext .txt file with a JSON-style representation of a dict. The dict must have the top-level key ``Vdata`` or two top-level keys, ``initial_Vdata`` and ``twotbn_Vdata``. For example:: {

(self, path)

    def load(self, path):
        '''
        Load node data from an input file located at *path*. Input file must be a plaintext .txt file with a JSON-style representation of a dict. The dict must have the top-level key ``Vdata`` or two top-level keys, ``initial_Vdata`` and ``twotbn_Vdata``. For example:: 

            {
                "Vdata": {
                    "<vertex 1>": <dict containing vertex 1 data>,
                    ...
                    "<vertex n>": <dict containing vertex n data>
                }
            }

        or::

            {
                "initial_Vdata": {
                    "<vertex 1>": <dict containing vertex 1 data>,
                    ...
                    "<vertex n>": <dict containing vertex n data>
                }
                "twotbn_Vdata": {
                    "<vertex 1>": <dict containing vertex 1 data>,
                    ...
                    "<vertex n>": <dict containing vertex n data>
                }
            }
            
        The function takes the following arguments:
            1. *path* -- The path to the text file that contains input data (e.g., "mydictionary.txt")
        
        In the static case, it modifies *Vdata* to hold the dictionary found at path. In the dynamic case, it modifies the *initial_Vdata* and *twotbn_Vdata* attributes to hold the dictionaries found at path.
