replaceAll

open override fun replaceAll(operator: UnaryOperator<E>)

Replace every element by applying the given operator and update weights accordingly.

Implementation notes:

Computes new element array and weights first.
Validates that all new weights are within bounds and that the resulting weights array is non-decreasing. If validation fails, an IllegalStateException is thrown and no mutation occurs.
If validation passes, internal arrays are overwritten in bulk.

operator

mapping function from old element to new element

if any replacement yields an out-of-bounds weight or the resulting weights are not non-decreasing
