Method Summary

Modifier and Type	Method	Description
`void`	`add(I i, double val)`	Adds an item-value pair to the list.
`default void`	`add(org.ranksys.core.util.tuples.Tuple2od<I> tuple)`	Adds an item-value tuple to the list.
`double`	`norm(I i, double value)`	Given an item-value pair, it computes the normalized value.
`default double`	`norm(org.ranksys.core.util.tuples.Tuple2od<I> tuple)`	Given an item-value pair, it computes the normalized value.
