Detailed Description

This is a C++ representation of a plugin.

It will load an Elektra plugin using the module loader from Elektra.

Then you can either check the plugins configuration using loadInfo(), parse() and check. Symbols can then be retrieved with getSymbol().

Or you can use the normal open(), close(), get(), set() and error() API which every plugin exports.

Member Function Documentation

◆ check()

void kdb::tools::Plugin::check ( std::vector< std::string > & warnings )

Does various checks on the Plugin and throws exceptions if something is not ok.

Check if Plugin is compatible to current Version of Backend-API.

Exceptions

PluginCheckException if there are errors

Parameters

warnings for warnings

Precondition: parse()

◆ close()

int kdb::tools::Plugin::close ( kdb::Key & errorKey )

Calls the close function of the plugin.

Precondition: parse()

◆ error()

int kdb::tools::Plugin::error	(	kdb::KeySet &	ks,
		kdb::Key &	parentKey
	)

Calls the error function of the plugin.

Precondition: parse()

◆ findInfo()

bool kdb::tools::Plugin::findInfo	(	std::string	check,
		std::string	item,
		std::string	section = `"infos"`
	)

Searches within a string of an information item.

Precondition: loadInfo()

◆ get()

int kdb::tools::Plugin::get	(	kdb::KeySet &	ks,
		kdb::Key &	parentKey
	)

Calls the get function of the plugin.

Precondition: parse()

◆ getConfig()

kdb::KeySet kdb::tools::Plugin::getConfig ( )

return the plugin config

Returns: the config supplied with constructor

See also: getNeededConfig()

◆ getFullName()

std::string kdb::tools::Plugin::getFullName ( )

Returns: the fullname of the plugin

◆ getInfo()

kdb::KeySet kdb::tools::Plugin::getInfo ( )

inline

Returns the whole keyset of information.

Precondition: loadInfo()

◆ getNeededConfig()

kdb::KeySet kdb::tools::Plugin::getNeededConfig ( )

In the plugin's contract there is a description of which config is needed in order to work together with a backend properly.

Returns: the keyset with the config needed for the backend.

See also: getConfig()

Precondition: loadInfo()

◆ getSymbol()

func_t kdb::tools::Plugin::getSymbol ( std::string which )

inline

Returns symbol to a function.

Precondition: parse()

◆ loadInfo()

void kdb::tools::Plugin::loadInfo ( )

Gets the configuration for the plugin.

(will be done in Modules.load)

◆ lookupInfo()

std::string kdb::tools::Plugin::lookupInfo	(	std::string	item,
		std::string	section = `"infos"`
	)

Gets the whole string of an information item.

Precondition: loadInfo()

◆ name()

std::string kdb::tools::Plugin::name ( )

Returns: the name of the plugin (module)

◆ open()

int kdb::tools::Plugin::open ( kdb::Key & errorKey )

Calls the open function of the plugin.

Precondition: parse()

◆ parse()

void kdb::tools::Plugin::parse ( )

Creates symbol and info table.

(will be done in Modules.load)

◆ set()

int kdb::tools::Plugin::set	(	kdb::KeySet &	ks,
		kdb::Key &	parentKey
	)

Calls the set function of the plugin.

Precondition: parse()
