Increment by N, return current

Atomically adds the given value to the current value and returns the updated (current) value of the counter. Multiple concurrent client requests are guaranteed to return updated value.

// *******************************************
// Backendless.Counters approach
// *******************************************
Backendless.Counters.addAndGet( counterName, value )
 .then( function( result ) {
 })
 .catch( function( error ) {
 });

// *******************************************
// Backendless.Counters.of() approach
// *******************************************
var counter = Backendless.Counters.of( counterName );
counter.addAndGet( value )
 .then( function( result ) {

 .catch( function( error ) {

where:

Argument                Description
counterName name of the counter to increment.
value number to add to the current counter value

Example

var successCallback = function( response ) {
  console.log( "counter value is - " + response );
};

var failureCallback = function( fault ) {
  console.log( "error - " + fault.message );
};

// ************************************************
// Backendless.Counters approach
// ************************************************
Backendless.Counters.addAndGet( "my counter", 1000 )
 .then( successCallback )
 .catch( failureCallback );

// ************************************************
// Backendless.Counters.of() approach
// ************************************************
var myCounter = Backendless.Counters.of( "my counter" );
myCounter.addAndGet( 1000 )
 .then( successCallback )
 .catch( failureCallback );
