:mrdocs:

This component‐private class provides a function object used to encode values that satisfy one of the `bdlat` type‐category concepts.

== Synopsis

Declared in `<baljsn_encodeimplutil.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class FORMATTER>
class EncodeImplUtil_ValueDispatcher;
----

== Description

This class's constructor closes over the `formatter`, `logStream`, and `options` parameters that are shared between all encoding operations provided in this component. The function‐call operator of this class provides an overload set that accepts an object that satisfies one of the `bdlat` type‐category concepts, and a `bdlat_TypeCategory` tag type that corresponds to the object's `bdlat` type category. Each function‐call‐operator overload encodes a JSON representation of the specified value to the `formatter` supplied on construction.
