Detailed Description

Helping methods for parsing of command line arguments and reading a configuration file. Any errors are reported by throwing a ProcessError exception which contains a description about the failure.

◆ getLoadTime()

static const std::chrono::time_point<std::chrono::system_clock>& OptionsIO::getLoadTime ( )

inlinestatic

Return the time stamp of the last init.

Here is the caller graph for this function:

◆ getOptions()

void OptionsIO::getOptions ( const bool commandLineOnly = false )

static

Parses the command line arguments and loads the configuration.

Command line arguments are parsed, first, throwing a ProcessError if something fails. Then options are reset to being writeable and the configuration is loaded using "loadConfiguration". After this, the options are reset again and the command line arguments are reparsed.

This workflow allows to read the name of a configuration file from command line arguments, first, then to load values from this configuration file and reset them by other values from the command line.

Here is the caller graph for this function:

◆ getRoot()

std::string OptionsIO::getRoot ( const std::string & filename )

static

Retrieves the XML root element of a supposed configuration or net.

Parameters

[in] filename the XML file to parse

Returns: the root element if any

Here is the caller graph for this function:

◆ loadConfiguration()

void OptionsIO::loadConfiguration ( )

static

Loads and parses the configuration.

The name of the configuration file is extracted from the global OptionsCont ("configuration-file" is used as the name of the option to get the name of the configuration).

◆ setArgs() [1/2]

void OptionsIO::setArgs ( const std::vector< std::string > & args )

static

Stores faked command line arguments for later parsing.

Parameters

[in] args arguments given as substitute for the command line

◆ setArgs() [2/2]

void OptionsIO::setArgs	(	int	argc,
		char **	argv
	)

static

Stores the command line arguments for later parsing.

Parameters
