Description: An object uses to display the load balance group number which can get in batch operation.

The sum of the batch load balance group start number and the batch load balance group number should not be larger than the total load balance group number in the system, so the real batch load balance group number maybe not equal to the setting batch load balance group number. no matter how the real batch load balance group number is the batch load balance group return number. For example, the setting batch load balance group start number is 3, the setting batch load balance group number is 4 and the total load balance group number in the system is 5, the real batch load balance group number would be 2, and the batch load balance group return number must be 2, the batch load balance group return number isn't equal to the batch load balance group number, otherwise, the total load balance group number in the system is 7, the real batch load balance group number would be 4, and the batch load balance group return number must be 4 too, the batch load balance group return number is equal to the batch load balance group number.
