ros::Publisher swri::advertise	(	ros::NodeHandle &	nh,
		const std::string	name,
		uint32_t	queue_size,
		bool	latched = `false`
	)

Definition at line 37 of file publisher.h.

int swri::comparePrefix	(	std::string const &	string,
		std::string const &	prefix
	)		`[inline]`

Determines whether `prefix` is a prefix of `string`.

Parameters:

string	The longer string to check, which may begin with the characters of `prefix`.
prefix	The shorter string, which may be a prefix of `string`.

Returns:: 0 if the first n characters of `string` are identical to `prefix`, where n is the length of `prefix`. 1 or -1 otherwise, according to the conventions of std::string::compare()

	)		`[inline, static]`

Definition at line 86 of file parameters.h.

static std::vector<std::string> swri::getUnusedParamKeys ( ros::NodeHandle const & n ) [inline, static]

Gets the list of parameters on the parameter server in the namespace of NodeHandle n that have not yet been got using any of the swri::param() or swri::getParam() functions.

The parameter keys are filtered by prefix, so if there exists a parameter /foo/bar/baz and parameter /foo/bar has been got, then /foo/bar/baz will not be returned as an unused parameter.

Note that this function has no way of knowing about parameters got using the ros::param() and ros::getParam() functions.

Parameters:

n	Nodehandle defining the namespace to restrict the list

Returns:: A vector of fully-qualified parameter names in n's namespace that haven't been got.

Definition at line 224 of file parameters.h.

bool swri::isPrefixOf	(	std::string const &	string,
		std::string const &	prefix
	)		`[inline]`

Boolean wrapper around comparePrefix.

Parameters:

string	The longer string to check, which may begin with the characters of `prefix`.
prefix	The shorter string, which may be a prefix of `string`.

Returns:: True if the first n characters of `string` are identical to `prefix`, where n is the length of `prefix`, false otherwise.

int swri::prefixLessThan	(	std::string const &	string,
		std::string const &	prefix
	)		`[inline]`

Less-than wrapper around comparePrefix, for algorithms that require a less-than comparator, such as sorting.

Parameters:

string	The longer string to check, which may begin with the characters of `prefix`.
prefix	The shorter string, which may be a prefix of `string`.

Returns:: True if the first n characters of `string` are "less than" the first n to `prefix`, where n is the length of `prefix`, according to the conventions of std::string::compare(). False otherwise.

Definition at line 202 of file parameters.h.

static void swri::warnUnusedParams ( ros::NodeHandle const & n ) [inline, static]

Wrapper around getUnusedParamKeys that emits a warning for every unused parameter

Parameters:

n	Nodehandle defining the namespace to restrict the list

Definition at line 267 of file parameters.h.
