typedef std::unordered_map<std::string, std::string> mx::app::iniFile::nameMapT

the unordered map type used for storing values.

Member Function Documentation

count()

size_t mx::app::iniFile::count ( const std::string &  section, const std::string &  name  )

inline

Get the number of entries for the given section and name.

Is either 1 or 0, depending on if this cconfig key exists.

Returns

the number of entries for the section=name key.

Parameters

[in]	section	The section for the key
[in]	name	the name for the key

erase()

int mx::app::iniFile::erase ( const std::string &  section, const std::string &  name  )

inline

Erase the entry for the given section and name.

Returns

0 on sucess

-1 if no section=name entry in the map.

Parameters

[in]	section	The section for the key
[in]	name	the name for the key

handler()

static int mx::app::iniFile::handler ( void *  user, const char *  section, const char *  name, const char *  value  )

inlinestatic

Config entry handler for the parser.

Calls insert, and returns its result. Any non-zero return will cause ini_parse to report the current line number as an error.

Returns

1 on success

0 on error

Parameters

[in]	user	a pointer to this.
[in]	section	the section of the config entry
[in]	name	the name of the config entry
[in]	value	the value of the config entry

Definition at line 126 of file iniFile.hpp.

insert()

int mx::app::iniFile::insert ( const char *  section, const char *  name, const char *  value  )

inline

Insert a config value. Appends if the key already exists in the map.

Todo:

need error checking.

Returns

0 on success

-1 on error.

Parameters

[in]	section	The section for the key
[in]	name	the name for the key
[in]	value	the value to insert

makeKey()

static std::string mx::app::iniFile::makeKey ( const std::string &  section, const std::string &  name  )

inlinestatic

Return a key generated from the section and name.

Constructs the key as "section=name".

Returns

the created key.

Parameters

[in]	section	The section for the key
[in]	name	the name for the key

operator()() [1/2]

std::string mx::app::iniFile::operator() ( const std::string &  name )

inline

Get the value associated with this name with an empty section.

Returns

the value if the section=name key exists, with section empty

and empty string if the section=name key does not exist, with section empty.

Parameters

[in]

name

the name for the key

operator()() [2/2]

std::string mx::app::iniFile::operator() ( const std::string &  section, const std::string &  name  )

inline

Get the value associated with this section=name pair.

Returns

the value if the section=name key exists

and empty string if the section=name key does not exist.

Parameters

[in]	section	The section for the key
[in]	name	the name for the key

parse()

int mx::app::iniFile::parse ( const std::string &  fname )

inline

Calls the inih parse function with this->handler.

This returns the result of the ini_parse function.

Returns

0 on success

>0 is the line number of the first parsing error

-1 on file open error

-2 on memory allocation error

Parameters

[in]

fname

the full path of the file

parseKey()

static int mx::app::iniFile::parseKey ( std::string &  section, std::string &  name, const std::string &  key  )

inlinestatic

Parse a key into its section and name consituents.

Requires that = be present.

Returns

0 on success

-1 on error, if no = found.

Parameters

[out]	section	the section extracted from the key
[out]	name	the name extracted from the key
[in]	key	th key to parse.
