edn-java is an parser and printer for 'edn' written in Java, for Java and requiring no external dependencies.

There is a newer version: 0.7.1

/**
 * This package provides the basis for implementing the printer.
 *
 * A protocol is a function (method) of which implementations can
 * be provided for any number of types.
 *
 * What this package provides is not quite a protocol, but
 * something a bit more general: a kind of Map which looks up values
 * by keys. The values can be of any type, but the keys must be of
 * type {@link java.lang.Class}. The trick here is that lookup takes
 * inheritance into account such that we don't need to specify an
 * implementation for every concrete type we expect to encounter.
