Increment by 1, return current¶
Atomically increments 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.

where:
Argument | Description |
---|---|
counterName |
name of the counter to increment. |
T |
numeric type for the counter values. Can be an instance of byte , short , int , float , long and double . |
callback |
the callback used for asynchronous calls to indicate that the operation has either successfully completed or resulted in error. |
Example¶
AsyncCallback<int> callback = new AsyncCallback<int>(
result =>
{
System.Console.WriteLine( "[ASYNC] counter value is - " + result );
},
fault =>
{
System.Console.WriteLine( "Error - " + fault );
} );
Backendless.Counters.IncrementAndGet( "my counter", callback );
IAtomic<int> myCounter = Backendless.Counters.Of<int>( "my counter" );
int counter = myCounter.IncrementAndGet();
System.Console.WriteLine( "[SYNC] counter value through IAtomic is - " + counter );
counter = Backendless.Counters.IncrementAndGet( "my counter" );
System.Console.WriteLine( "[SYNC] counter value is - " + counter );
long longCounter = Backendless.Counters.IncrementAndGet<long>( "my counter" );
System.Console.WriteLine( "[SYNC] counter value is - " + longCounter );
