std::string RTC::ModuleManager::load ( const std::string & file_name )

Load the module.

Load file_name as DLL or a shared liblary. The file_name is specified by the relative path to default load path (manager.modules.load_path).

If Property manager.modules.abs_path_allowed is yes, the load module can be specified by the absolute path.
If Property manager.modules.download_allowed is yes, the load module can be specified with URL.

The file_name can be specified by the absolute path. If manager.modules.abs_path_allowed is no, module of file_name will be searched from the default module load path and loaded.

Parameters

file_name The target module name for the loading

Returns: Name of module for the specified load

std::string RTC::ModuleManager::load	(	const std::string &	file_name,
		const std::string &	init_func
	)

Load and intialize the module.

Load the specified file as DLL or a shared library, and execute operation for specified initialization.

Parameters

file_name	The target module name for the loading
init_func	Operation for initialization

Returns: Name of module for the specified load

void RTC::ModuleManager::removeInvalidModules ( )

protected

Removing incalid module profiles.

Referenced by disallowModuleDownload().

void RTC::ModuleManager::setLoadpath ( const std::vector< std::string > & load_path )

Set the module load path.

Specify searching path to find the target module when loading module.

Parameters

load_path List of module search path

void* RTC::ModuleManager::symbol	(	const std::string &	file_name,
		const std::string &	func_name
	)
throw	(	ModuleNotFound,
		SymbolNotFound
	)

Refer to the symbol of the module.

void RTC::ModuleManager::unload ( const std::string & file_name )

Unload the module.

Close and unload the specified module that has been loaded.

Parameters

file_name Name of module for the unloading

void RTC::ModuleManager::unloadAll ( )
