static void geotess::CPPUtils::getProperties	(	const string &	str,
		map< string, string > &	props
	)

static

Retrieves all properties defined in the input string str and saves them into the property map props.

The properties must be of the form "name = value; name = value; ..." where the name value associations are set into the property map. All "names" are lower-cased into the property map. "values" are simply assigned without case change. All name and value pairs are stripped of leading and trailing blanks before placement into the property map. All properties must be separated by a semi-colon.

Parameters

str	Input semicolon separated string of properties.
props	Input map that will be filled with the properties name –> value associations.

static bool geotess::CPPUtils::getProperty	(	const map< string, string > &	props,
		const string &	tag,
		string &	value
	)

static

Retrieves the "value" associated with "tag" from the property map "props".

If the "tag" is found in props then true is returned and "value" is set. Otherwise, false is returned.

Parameters

props	The input properties map (name = value).
tag	The input key for which an associated value will be sought.
value	The returned value associated with the input tag ... if one was found.

Returns: True if the value was set.
