- to check if the array was successfully parsed, or
- to check if the array was successfully allocated.

bool success() const; Return value
true if the array was successfully parsed/allocated. false if the parsing/allocation failed.
Examples
Example 1: parsing success:
StaticJsonBuffer<200> jsonBuffer; JsonArray& array = jsonBuffer.parseArray("[1,2]"); Serial.println(array.success()); // true Example 2: parsing failure:
StaticJsonBuffer<200> jsonBuffer; JsonArray& array = jsonBuffer.parseArray("{1,2}"); Serial.println(array.success()); // false Example 3: allocation success:
StaticJsonBuffer<200> jsonBuffer; JsonArray& array = jsonBuffer.createArray(); Serial.println(array.success()); // true Example 4: allocation failure:
StaticJsonBuffer<1> jsonBuffer; JsonArray& array = jsonBuffer.createArray(); Serial.println(array.success()); // false
