Description

A collection of JsonVariant

The constructor is private, you cannot instantiate a JsonArray directly. Instead, you must use JsonBuffer::createArray().

Because the memory of a JsonArray is located a JsonBuffer, you always manipulate it through reference and you cannot copy it.

Example

StaticJsonBuffer<200> jsonBuffer;

// create an empty array
JsonArray& array1 = jsonBuffer.createArray();

// parse a JSON array
char json[] = "[1,2,3]";
JsonArray& array2 = jsonBuffer.parseArray(json);
