This is the detailed documentation of every class and function of the ArduinoJson library. Some parts have been simplified to be easier to understand, so if you look at the source code, you might see some differences.

Entities

JsonArray
Stores an array of JsonVariant
JsonObject
Stores a collection of key-value pair where each key is a string and each value is a JsonVariant
JsonVariant
Stores any kind of value allowed in a JSON document: int, float, array, object…

Utilities

JsonBuffer
Owns the memory for JsonArray and JsonObject
RawJson()
Allows to insert preformatted pieces in a JSON document
ARDUINOJSON_VERSION
Tells which version of ArduinoJson is installed
