Comparators.comparing doesn't handle nulls (original) (raw)

Would you be more specific?

Comparators.comparing is not taking null as arguments. As how the returned Comparator compare nulls is really depends on Comparator itself. The Comparable style comparator won't handle null as Comparable doesn't support null.

Hi guys,

In most usages of Guava's ComparisonChain / Ordering that I am trying to replace with Comparator, nulls are involved. Comparators.comparing provides no easy way of handling this except by writing verbose code. Any plans to improve on that? Regards, Michael
