tokenize()

template<typename T >

void MooseUtils::tokenize	(	const std::string &	str,
		std::vector< T > &	elements,
		unsigned int	min_len = 1,
		const std::string &	delims = "/"
	)

This function will split the passed in string on a set of delimiters appending the substrings to the passed in vector.

The delimiters default to "/" but may be supplied as well. In addition if min_len is supplied, the minimum token length will be greater than the supplied value. T should be std::string or a MOOSE derived string class.

bool MooseUtils::tokenizeAndConvert	(	const std::string &	str,

tokenizeAndConvert splits a string using delimiter and then converts to type T.

If the conversion fails tokenizeAndConvert returns false, otherwise true.
