Detailed Description

Configuration data structure. Inspired by rviz's use of wxConfigBase. Current implementation uses a flat ordered map, but in the long run it may more sense to use a recursive data structure.

void rviz::Config::read

(

std::istream &

input

)

Read settings from a stream. Invalid lines are ignored.

Definition at line 68 of file config.cpp.

bool rviz::Config::readFromFile

(

const std::string &

filename

)

Returns:

success or failure of the initial file-open.

Definition at line 38 of file config.cpp.

void rviz::Config::set	(	const std::string &	key,
		int	value
	)

Definition at line 258 of file config.cpp.

void rviz::Config::set	(	const std::string &	key,
		float	value
	)

Definition at line 251 of file config.cpp.

void rviz::Config::set	(	const std::string &	key,
		const std::string &	value
	)			[inline]

Definition at line 59 of file config.h.

const std::string rviz::Config::stripFirstSlash

(

const std::string &

str

)

[private]

If the first char of str is a '/', return everything but the first char in a new string. If it is not, return str.

Definition at line 311 of file config.cpp.

std::string rviz::Config::unescapeKey

(

const std::string &

cooked_key

)

[private]

Definition at line 224 of file config.cpp.

void rviz::Config::unset

(

const std::string &

key

)

[inline]

Remove a key/value pair. This will invalidate iterators pointing at the given element.

Definition at line 65 of file config.h.

void rviz::Config::write

(

std::ostream &

output

)

Write settings to a stream.

Definition at line 110 of file config.cpp.

		const std::string &	new_dir,
		const std::string &	prev_dir
	)			[private]

Write a directory description of new_dir to output, given that we were previously "in" prev_dir.

Definition at line 165 of file config.cpp.

bool rviz::Config::writeToFile

(

const std::string &

filename

)

Returns:

success or failure of the initial file-open.
