Arduino JSON: change log
|
||||
========================
|
||||
|
||||
v3.0
|
||||
----
|
||||
|
||||
* New parser API, see bellow
|
||||
* Renamed `JsonHashTable` into `JsonObject`
|
||||
* Added iterators for `JsonArray` and `JsonObject`
|
||||
|
||||
Old parser API:
|
||||
|
||||
JsonHashTable root = parser.parseHashTable(json);
|
||||
|
||||
char* sensor = root.getString("sensor");
|
||||
long time = root.getLong("time");
|
||||
double latitude = root.getArray("data").getDouble(0);
|
||||
double longitude = root.getArray("data").getDouble(1);
|
||||
|
||||
New parser API:
|
||||
|
||||
JsonObject root = parser.parse(json);
|
||||
|
||||
char* sensor = root["sensor"];
|
||||
long time = root["time"];
|
||||
double latitude = root["data"][0];
|
||||
double longitude = root["data"][1];
|
||||
|
||||
v2.1

"Parser size" was measured with a program parsing `{"sensor":"outdoor","value":25.6}`.
|
||||
For each library, I wrote a program that extracts a string and a float. I subtracted the size of a program doing the same without any JSON parsing involved. [Source files are here](https://gist.github.com/bblanchon/e8ba914a7109f3642c0f).
