Evil Java Interop

rontgen

Leiningen dependency (Clojars): [rontgen "1.000000000001.0"].

Röntgen is sharp, dangerous, and highly opinionated java interop. Röntgen can peer upon any java instance, returning an immutable map that shows the state of all the fields of that instance. Röntgen can also bash into any java instance an immutable map of values, destructively modifying the instance in order to push data in place.

Röntgen ignores private and protected modifiers for fields.

Usage

#inst "1970-01-01T00:00:06.000-00:00"
