template<typename BasicJsonType , typename SAX = json_sax_dom_parser<BasicJsonType>>
get next character from the input
This function provides the interface to the used input adapter. It does not throw in case the input reached EOF, but returns a -'ve valued std::char_traits<char>::eof()
in that case.
- Returns
- character read from the input

template<typename BasicJsonType , typename SAX = json_sax_dom_parser<BasicJsonType>>
Parses a C-style string from the BSON input.
- Parameters
-
[in,out] | result | A reference to the string variable where the read string is to be stored. |
- Returns
true
if the -byte indicating the end of the string was encountered before the EOF; false` indicates an unexpected EOF.

template<typename BasicJsonType , typename SAX = json_sax_dom_parser<BasicJsonType>>
template<typename NumberType >
Parses a zero-terminated string of length len from the BSON input.
- Parameters
-
[in] | len | The length (including the zero-byte at the end) of the string to be read. |
[in,out] | result | A reference to the string variable where the read string is to be stored. |
- Template Parameters
-
NumberType | The type of the length len |
- Precondition
- len >= 1
- Returns
true
if the string was successfully parsed

template<typename BasicJsonType , typename SAX = json_sax_dom_parser<BasicJsonType>>
reads a CBOR string
This function first reads starting bytes to determine the expected string length and then copies this number of bytes into a string. Additionally, CBOR's strings with indefinite lengths are supported.
- Parameters
-
[out] | result | created string |
- Returns
- whether string creation completed

template<typename BasicJsonType , typename SAX = json_sax_dom_parser<BasicJsonType>>
reads a MessagePack string
This function first reads starting bytes to determine the expected string length and then copies this number of bytes into a string.
- Parameters
-
[out] | result | created string |
- Returns

template<typename BasicJsonType , typename SAX = json_sax_dom_parser<BasicJsonType>>
template<typename NumberType >
create a string by reading characters from the input
- Template Parameters
-
NumberType | the type of the number |
- Parameters
-
[in] | format | the current format (for diagnostics) |
[in] | len | number of characters to read |
[out] | result | string created by reading len bytes |
- Returns
- whether string creation completed
- Note
- We can not reserve len bytes for the result, because len may be too large. Usually, unexpect_eof() detects the end of the input before we run out of string memory.

template<typename BasicJsonType , typename SAX = json_sax_dom_parser<BasicJsonType>>
determine the type and size for a container
In the optimized UBJSON format, a type and a size can be provided to allow for a more compact representation.
- Parameters
-
[out] | result | pair of the size and the type |
- Returns
- whether pair creation completed

template<typename BasicJsonType , typename SAX = json_sax_dom_parser<BasicJsonType>>
reads a UBJSON string
This function is either called after reading the 'S' byte explicitly indicating a string, or in case of an object key where the 'S' byte can be left out.
- Parameters
-
[out] | result | created string |
[in] | get_char | whether a new character should be retrieved from the input (true, default) or whether the last read character should be considered instead |
- Returns
- whether string creation completed

template<typename BasicJsonType , typename SAX = json_sax_dom_parser<BasicJsonType>>
Read a BSON element list (as specified in the BSON-spec)
The same binary layout is used for objects and arrays, hence it must be indicated with the argument is_array which one is expected (true –> array, false –> object).
- Parameters
-
[in] | is_array | Determines if the element list being read is to be treated as an object (is_array == false), or as an array (is_array == true). |
- Returns
- whether a valid BSON-object/array was passed to the SAX parser
