- to check if the object was successfully parsed, or
- to check if the object was successfully allocated.
Signatures
bool success() const; Return value
true if the object was successfully parsed/allocated. false if the parsing/allocation failed.
Examples
Example 1: parsing success:
StaticJsonBuffer<200> jsonBuffer; JsonObject& object = jsonBuffer.parseObject("{\"hello\":\"world\"}"); Serial.println(object.success()); // true Example 2: parsing failure:
StaticJsonBuffer<200> jsonBuffer; JsonObject& object = jsonBuffer.parseObject("[\"hello\",\"world\"]"); Serial.println(object.success()); // false Example 3: allocation success:
StaticJsonBuffer<200> jsonBuffer; JsonObject& object = jsonBuffer.createObject(); Serial.println(object.success()); // true Example 4: allocation failure:
StaticJsonBuffer<1> jsonBuffer; JsonObject& object = jsonBuffer.createObject(); Serial.println(object.success()); // false
