Field Paths

Field paths are a special syntax for describing document positions within the 0-Meter configuration files.

JSON fields can be contained either in lists or in objects. A field path might look like this:

responses[0.codes[1

The use of [ signifies an array, and the use of . signifies an object. Here’s the JSON message this would parse:

{responses: [{codes: [0, 1]}]}

The above field path would return the value ‘1’ from the response message.
