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);
