Getting value from json-spirit

I'm using the Json-Spirit library, however i'm unsure how to read value from an object, without iterating over each of the name-value pairs.

If i have an object such that: 

{
    "boids":
    {
        "width": 10,
        "count": 5,
        "maxSpeedMin": 2,
        "maxSpeedMax": 80,
        "maxForceMin": 0.5,
        "maxForceMax": 40
    }
}

How can I access, for example, the width value by name?

Solution

  • json_spirit added support for std::map so that you can look up a value.

    One of the projects in the json_spirit download is json_map_demo. This will help you to understand it better.
