:relfileprefix: ../../
:mrdocs:

This class provides a mechanism for copying the constituent values of certain `bdlat`‐compatible objects to `bdljsn::Json` objects, and vice versa.

== Synopsis

Declared in `<baljsn_jsonconverter.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
class JsonConverter;
----

== Description

In each case, the resulting object is a different representation of the data in the original. This conversion is analogous to the encoding and decoding operations provided elsewhere in this package; however, the `convert` methods here avoid the creation of any textual representation of the data.

The `bdlat` objects must meet the requirements of a sequence, choice, or array as defined in `bdlat_sequencefunctions`, `bdlat_choicefunctions`, and `bdlat_arrayfunctions` components, respectively.
