basic_ubjson_encoder
is noncopyable and nonmoveable.
Four specializations for common character types and result types are defined:
Type | Definition |
---|---|
ubjson_stream_encoder | basic_ubjson_encoderjsoncons::binary_stream_sink |
ubjson_bytes_encoder | basic_ubjson_encoder<jsoncons::bytes_sink<std::vector<uint8_t>>> |
Type | Definition |

char_type | char |
sink_type | Sink |
string_view_type |
explicit basic_ubjson_encoder(Sink&& sink)
Constructs a new encoder that writes to the specified destination.
virtual ~basic_ubjson_encoder() noexcept
void reset();
Reset encoder to write another value to the same sink
void reset(Sink&& sink)
Reset encoder to write a new value to a new sink

(4) Indicates the end of an object.
Returns true
if the consumer wishes to receive more events, false
otherwise.
Throws a ser_error on parse errors.
(5) Indicates the beginning of an indefinite length array.
Returns true
if the consumer wishes to receive more events, false
otherwise.
Throws a ser_error on parse errors.
(6) Indicates the beginning of an array of known length.
Returns true
if the consumer wishes to receive more events, false
otherwise.
