Decrement by 1, return current¶
Atomically decrements by one the current value and returns the updated (current) value of the counter. Multiple concurrent client requests are guaranteed to return unique updated value.
Future<int> Backendless.counters.decrementAndGet(String counterName); IAtomic counter = Backendless.counters.of(String counterName); Future<int> counter.decrementAndGet();
where:
Argument | Description |
---|---|
counterName |
name of the counter to decrement. |
Example¶
Function callback = (counterValue) => print("current counter value is - $counterValue"); Backendless.counters.decrementAndGet("my counter").then(callback); IAtomic myCounter = Backendless.counters.of("my counter"); myCounter.decrementAndGet().then(callback);
