Jackson 2.18.2 · com.fasterxml.jackson.dataformat.javaprop.util.JPropNode

Value in an ordered tree presentation built from an arbitrarily ordered set of flat input values. Since either index- OR name-based access is to be supported (similar to, say, Javascript objects) -- but only one, not both -- storage is bit of a hybrid. In addition, branches may also have values. So, code does bit coercion as necessary, trying to maintain something consistent and usable at all times, without failure.
