Typedef Documentation

MapObject

using helper::json::MapObject = typedef std::map<std::string, std::string>

std::map that represents simple JSON object.

This type can hold only JSON Objects that consist only from string values, other types are going to be ignored or converted.

Writer

template<typename T >

using helper::json::Writer = typedef rapidjson::Writer<T>

append_rapid_json_to_text()

template<template< typename > typename Writer = Writer, typename JsonValue >

void helper::json::append_rapid_json_to_text	(	JsonValue *	json_value,
		std::string &	text_value
	)

merge_objects() [1/2]

std::string helper::json::merge_objects	(	const std::string &	j1,
		const std::string &	j2,
		const std::set< std::string > &	skip_attributes
	)

merge_objects() [2/2]

rapid_json_to_text()

template<template< typename > typename Writer = Writer, typename JsonValue >

void helper::json::rapid_json_to_text	(	JsonValue *	json_value,
		std::string &	text_value
	)

text_to() [1/6]

template<typename Handler , typename Container >

bool helper::json::text_to	(	Handler *	handler,
		const Container &	c
	)

Convert text representation of json object/value to type defined by 'Handler'.

The 'Handler' must be a child class of rapidjson::BaseReaderHandler. The child class must contain type/alias definition of returned result, under "Result" alias and get_result method. For example:

class HandlerSomeExample
     : rapidjson::BaseReaderHandler<rapidjson::UTF8<>,HandlerSomeExample>

{ public: using Result = std::string;

    ...
 };

Handler::Result helper::json::text_to_handler	(	const Container &	c,
		HandlerArgs &&...	args
	)

Convert text representation of json object/value to type defined by 'Handler'.

The 'Handler' must be a child class of rapidjson::BaseReaderHandler. The child class must contain type/alias definition of returned result, under "Result" alias and get_result method. For example:

class HandlerSomeExample
     : rapidjson::BaseReaderHandler<rapidjson::UTF8<>,HandlerSomeExample>

{ public: using Result = std::string;
