Detailed Description

Classes to read or write a JSON file.

See below for an overview of the classes in this module.

Synopsis

This module handles JSON input and output. It supports the full Json syntax (including null values) with the addition of complex numbers represented as a nested JSON struct with fields "r" and "i".
NaN and infinite floating point numbers are written as a null value.
It supports comments in the JSON file using C, C++ or Python style delimiters.

It consists of the following classes:

• JsonOut to create and populate a JSON file. Besides support of scalar values and std::vector, it also supports Array, Record and ValueHolder objects.
• JsonParser to parse a JSON file and store the results in a JsonKVMap object. The parser only accepts the rather strict JSON number representation.
• JsonKVMap to obtain the results from a parsed JSON file. It is possible to obtain a (possible nested) sequence as an Array object.
