Detailed Description

A JSONNode wraps a cJSON object and presents useful functions for accessing the different properties of the json structure like operator[], isType() and asType() methods.

The main ways a user can build a JSONNode is from a json string, from a json file with loadFromFile or with the JSONBuilder.

Constructor & Destructor Documentation

◆ JSONNode() [1/4]

xrt::auxiliary::util::json::JSONNode::JSONNode ( cJSON *  cjson,
bool  is_owner,
const JSONNode::Ptr &  parent 
)
inline

This is public so that make_shared works; do not use outside of this file.

◆ JSONNode() [2/4]

xrt::auxiliary::util::json::JSONNode::JSONNode ( cJSON *  cjson)
inline

Wrap cJSON object for easy manipulation, does not take ownership.

◆ JSONNode() [3/4]

xrt::auxiliary::util::json::JSONNode::JSONNode ( )
inline

Makes a null object; isInvalid() on it returns true.

◆ JSONNode() [4/4]

xrt::auxiliary::util::json::JSONNode::JSONNode ( const string &  content)
inline

Receives a json string and constructs a wrapped cJSON object out of it.
