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.
-
compare
Description copied from interface:ComparatorVariable
It compares the metric of the left variable against the right one.- Specified by:
compare
in interfaceComparatorVariable<T extends Var>
- Parameters:
leftVar
- left variablerightVar
- right variable- Returns:
- 1 if metric for left variable is greater, 0 is they are equal, -1 if smaller.
-
metric
Description copied from interface:ComparatorVariable
It returns the metric of the variable given according to the comparator.- Specified by:
metric
in interfaceComparatorVariable<T extends Var>
- Parameters:
var
- variable for which metric is computed.- Returns:
- the metric of the variable according to the comparator.
