Detailed Description

This class can parse a json file containing a list of objects to be created and their wiring. Then it can populate a Catalog with that objects. The syntax of the json file should be similar to:

{

  "wallaroo":
  {

    "plugins":
    {
        "shared": "pluginName"
    },

    "parts":
    [
      {
        "name": "instance1",
        "class": "className1"
      },

      {
        "name": "instance2",
        "class": "className2",
        "attribute":
          {
            "name": "attr1_name",
            "value": "attr1_string_value"
          },
        "attribute":
          {
            "name": "attr2_name",
            "value": attr2_value
          }
      },
      
      {
        "name": "instance3",
        "class": "className3",
        "parameter1":
          {
            "type": "string",
            "value": "mystring"
          },
        "parameter2":
          {
            "type": "int",
            "value": 34
          }
      }
    ],

    "wiring":
    [
      {
        "source": "sourceInstance",
        "dest": "targetInstance",
        "collaborator": "collaboratorName"
      },

      {
        "source": "sourceInstance2",
        "dest": "targetInstance2",
        "collaborator": "collaboratorName2"
      }
