UniValue
Summary
A universal value class, with JSON encoding and decoding.
UniValue is an abstract data type that may be a null, boolean, string, number, array container, or a key/value dictionary container, nested to an arbitrary depth.
This class is aligned with the JSON standard, RFC 7159.
Library usage
This is a fork of univalue used by Bitcoin Core. It is not maintained for usage by other projects. Notably, the API is broken in non-backward-compatible ways.
Other projects looking for a maintained library should use the upstream univalue at https://github.com/jgarzik/univalue.
