构造及析构函数说明

serializer()

template<typename BasicJsonType>

serializer ( output_adapter_t< char > s, const char ichar, error_handler_t error_handler_ = error_handler_t::strict )

inline

参数

[in]	s	output stream to serialize to
[in]	ichar	indentation character to use
[in]	error_handler_	how to react on decoding errors

成员函数说明

dump()

template<typename BasicJsonType>

void dump ( const BasicJsonType & val, const bool pretty_print, const bool ensure_ascii, const unsigned int indent_step, const unsigned int current_indent = 0 )

inline

internal implementation of the serialization function

This function is called by the public member function dump and organizes the serialization internally. The indentation level is propagated as additional parameter. In case of arrays and objects, the function is called recursively.

• strings and object keys are escaped using escape_string()
• integer numbers are converted implicitly via operator<<
• floating-point numbers are converted to a string using "g" format
• binary values are serialized as objects containing the subtype and the byte array

参数

[in]	val	value to serialize
[in]	pretty_print	whether the output shall be pretty-printed
[in]	ensure_ascii	If ensure_ascii is true, all non-ASCII characters in the output are escaped with \uXXXX sequences, and the result consists of ASCII characters only.
[in]	indent_step	the indent level
[in]	current_indent	the current indent level (only used internally)
