#include <JSONDump.hpp>

Details:

BSON -> JSON Dump.

Provides an std::ostream comparable output operator for dumping a JSON representation of the given BSON object. JSONDump implements interface IBSONObjectVisitor and uses the BSON object parsing events to output the BSON object's JSON representation.
