Detailed Description

Base class for representing user preferences a la windows INI files.

The real implementation is in Python, and is accessible from C++ via the magic of SWIG directors.

Constructor & Destructor Documentation

prefs()

gr::prefs::prefs

(

)

Creates an object to read preference files.

If no file name is given (empty arg list or ""), this opens up the standard GNU Radio configuration files in prefix/etc/gnuradio/conf.d as well as ~/.gnuradio/config.conf.

Only access this through the singleton defined here:

prefs *p = prefs::singleton();

Member Function Documentation

_read_files()

void gr::prefs::_read_files ( const std::vector< std::string > &  filenames )

protected

_sys_prefs_filenames()

std::vector<std::string> gr::prefs::_sys_prefs_filenames ( )

protected

add_config_file()

void gr::prefs::add_config_file

(

const std::string &

configfile

)

If specifying a file name, this opens that specific configuration file of the standard form containing sections and key-value pairs:

[SectionName]
key0 = value0
key1 = value1

get_bool()

bool gr::prefs::get_bool	(	const std::string &	section,
		const std::string &	option,

get_double()

double gr::prefs::get_double	(	const std::string &	section,
		const std::string &	option,
		double	default_val
	)

If option exists and value can be converted to double, return it; else default_val.

protected

get_long()

long gr::prefs::get_long	(	const std::string &	section,
		const std::string &	option,

Does option exist?

has_section()

bool gr::prefs::has_section

(

WARNING: this will overwrite your current config.conf file.

set_bool()

void gr::prefs::set_bool	(	const std::string &	section,
		const std::string &	option,
		bool	val
	)

Set or add a bool option to section with value val.

		double	val
	)

Set or add a double option to section with value val.
