convert()

template<class T >

bool MooseUtils::convert	(	const std::string &	str,
		T &	value,
		const bool	throw_on_failure
	)

Takes the string representation of a value and converts it to the value.

For standard numeric types, this gets around the deficiencies in the STL stoi and stod methods where they might successfully convert part of a string to a number when we'd instead prefer to get a failure.

For string and string-derived types, this does a direct copy and does not utilize a stream.

For all other types, this uses the stringstream >> operator to fill the value.

Parameters

str	The string to convert from
value	The typed value to fill
throw_on_failure	If true, throw a std::invalid_argument on failure

Returns

Whether or not the conversion succeeded

shuffle() [1/4]

template<typename T >

void MooseUtils::shuffle	(	std::vector< T > &	data,
		MooseRandom &	generator,
		const std::size_t	seed_index = 0
	)

Shuffle function for serial or distributed vector of data that shuffles in place.

Parameters

data	The vector on which the values are to be swapped
generator	Random number generator to use for shuffle
seed_index	(default: 0) The seed index to use for calls to randl
comm_ptr	Optional Communicator, if provided and running with multiple processors the vector is assumed to be distributed

Both the serial and distributed version implement a Fisher-Yates shuffle https://en.wikipedia.org/wiki/Fisher%E2%80%93Yates_shuffle

NOTE: This distributed shuffle I have here does a parallel communication with each swap pair generated. I am certain that there are more efficient ways to shuffle a distributed vector, but there doesn't seem to be an algorithm in the literature (my search was not extensive).

The reason I came to this conclusion was because of a 2019 paper, which states the following (https://iopscience.iop.org/article/10.1088/1742-6596/1196/1/012035):

The study also says that the Fisher-Yates Shuffle can be developed in two ways,
namely the algorithm's initial assumptions that allow for discrete uniform variables,
and also with the avent of large core clusters and GPUs, there is an interest in making
parallel versions of this algorithm.

This paper discusses the MergeShuffle (https://arxiv.org/abs/1508.03167), but that is a shared memory parallel algorithm.

Hence, if you want to become famous create a parallel Fisher-Yates algorithm for MPI.

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 >= 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.
