JSON based APIs.
The ola::web namespace provides:
#include <ola/web/Json.h>
#include <ola/web/JsonWriter.h>
JsonObject obj;
obj.Add("name", "simon");
obj.Add("age", 10);
obj.Add("male", true);
JsonArray *friends = obj.AddArray("friends");
friends->Add("Peter");
friends->Add("Bob");
friends->Add("Jane");
const string output = JsonWriter::AsString(json);
#include <ola/web/Json.h> #include <ola/web/JsonParser.h> std::string error; JsonValue *value = JsonParser::Parse(json_string, &error);

Functions | |
| JsonObject * | ola::web::ObjectCast (JsonValue *value) |
| Downcast a JsonValue to a JsonObject. | |
| JsonArray * | ola::web::ArrayCast (JsonValue *value) |
| Downcast a JsonValue to a JsonArray. | |
| JsonArray * ola::web::ArrayCast | ( | JsonValue * | value | ) |
| JsonObject * ola::web::ObjectCast | ( | JsonValue * | value | ) |
Downcast a JsonValue to a JsonObject.
This should be used rather than dynamic_cast<JsonObject> since it doesn't rely on RTTI.
