compare
Description copied from interface:ComparatorVariable
It compares the baseline metric to the variable metric.- Specified by:
compare
in interfaceComparatorVariable<T extends Var>
- Parameters:
left
- the baseline for comparison.var
- variable which is compared to baseline.- Returns:
- 1 if metric is larger than variable, 0 if equal, -1 if baseline is smaller.
