template<typename BasicJsonType , typename InputAdapterType , 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_type>::eof() in that case.
- Returns
- character read from the input

template<typename NumberType >
create a byte array by reading bytes from the input
- Template Parameters
-
| NumberType | the type of the number |
- Parameters
-
| [in] | format | the current format (for diagnostics) |
| [in] | len | number of bytes to read |
| [out] | result | byte array created by reading len bytes |
- Returns
- whether byte array 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 memory.

template<typename BasicJsonType , typename InputAdapterType , typename SAX = json_sax_dom_parser<BasicJsonType>>
template<typename NumberType >
Parses a byte array input of length len from the BSON input.
- Parameters
-
| [in] | len | The length of the byte array to be read. |
| [in,out] | result | A reference to the binary variable where the read array is to be stored. |
- Template Parameters
-
| NumberType | The type of the length len |
- Precondition
- len >= 0
- Returns
true if the byte array was successfully parsed
Definition at line 8405 of file json.hpp.
template<typename BasicJsonType , typename InputAdapterType , 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
Definition at line 8384 of file json.hpp.
template<typename BasicJsonType , typename InputAdapterType , typename SAX = json_sax_dom_parser<BasicJsonType>>
reads a CBOR byte array
This function first reads starting bytes to determine the expected byte array length and then copies this number of bytes into the byte array. Additionally, CBOR's byte arrays with indefinite lengths are supported.
- Parameters
-
| [out] | result | created byte array |
- Returns
- whether byte array creation completed

- Parameters
-
| [out] | result | created byte array |
- Returns

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 InputAdapterType , 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
Definition at line 10130 of file json.hpp.
template<typename BasicJsonType , typename InputAdapterType , 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
Definition at line 9999 of file json.hpp.
template<typename BasicJsonType , typename InputAdapterType , 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
