This class provides a mechanism for decoding JSON data into value-semantic objects.
Declared in <baljsn_decoder.h>
class Decoder;The decode methods are function templates that will decode any object that meets the requirements of a sequence, choice, or array object as defined in the bdlat_sequencefunctions, bdlat_choicefunctions, and bdlat_choicefunctions components respectively. These generic frameworks provide a common compile-time interface for manipulating struct-like and union-like objects. In particular, the types generated by bas_codegen.pl provide the necessary interface and can be decoded using this component.
