basic_msgpack_encoder is noncopyable.

basic_msgpack_encoder

Four specializations for common character types and result types are defined:

Type Definition
msgpack_stream_encoder basic_msgpack_encoderjsoncons::binary_stream_sink
bson_bytes_encoder basic_msgpack_encoder<jsoncons::bytes_sink<std::vector<uint8_t>>>

Member types

Type Definition
char_type char
sink_type Sink
string_view_type

Constructors

explicit basic_msgpack_encoder(Sink&& sink)

Constructs a new encoder that writes to the specified destination.

Destructor

virtual ~basic_msgpack_encoder() noexcept

Member functions

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

Inherited from jsoncons::basic_json_visitor

(1) Flushes whatever is buffered to the destination.

(2) Indicates the begining of an object of indefinite length. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(3) Indicates the begining of an object of known length. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(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. Throws a ser_error on parse errors.

(7) Indicates the end of an array. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(8) Writes the name part of an object name-value pair. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(9) Writes a null value. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(10) Writes a boolean value. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(11) Writes a text string value. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(12) Writes a byte string value source with a generic tag. Type Source must be a container that has member functions data() and size(), and member type value_type with size exactly 8 bits (since 0.152.0.) Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(13) Writes a byte string value source with a format specific tag, ext_tag. Type Source must be a container that has member functions data() and size(), and member type value_type with size exactly 8 bits (since 0.152.0.) Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(14) Writes a non-negative integer value. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(15) Writes a signed integer value. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(16) Writes a half precision floating point value. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(17) Writes a double precision floating point value. Returns true if the consumer wishes to receive more events, false otherwise. Throws a ser_error on parse errors.

(18)-(33) Same as (2)-(17), except sets ec and returns false on parse errors.
