Doc from com.github.benmanes.caffeine.cache.Interner.intern.

Chooses and returns the representative instance for any collection of instances that are equal to each other. If two equal inputs are given to this method, both calls will return the same instance. That is, intern(a).equals(a) always holds, and intern(a) == intern(b) if and only if a.equals(b). Note that intern(a) is permitted to return one instance now and a different instance later if the original interned instance was garbage-collected.

Warning

Do not use with mutable objects.

Parameters
sample:E

the element to add if absent

Returns:E

the representative instance, possibly the sample if absent
