Detailed Description

Some functions to parse enums from (input-) strings.

Function Documentation

matchStrings()

std::string autopas::utils::StringUtils::matchStrings ( const std::vector< std::string > &  haystack, std::string  needle  )

inline

Finds best match of needle in haystack.

Needle is compared to every option in haystack and the Needleman-Wunsch score calculated. If the result is ambiguous an exception is thrown.

Parameters

haystack	Vector of string to match to.
needle

Returns

Best matching string.

parseArrayD3()

std::array< double, 3 > autopas::utils::StringUtils::parseArrayD3 ( const std::string &  string )

inline

Converts a string to std::array<double,3>.

Allowed delimiters can be found in autopas::utils::StringUtils::delimiters.

String format: 3 doubles(or ints) separated by delimiters (examples: 10.,10.,10.)

Parameters

string

String to parse.

Returns

parseBoolOption()

bool autopas::utils::StringUtils::parseBoolOption ( const std::string &  booleanOption )

inline

Converts a string to bool.

String format: on || off || enabled || disabled || true || false

Parameters

booleanOption

Returns

parseDoubles()

std::set< double > autopas::utils::StringUtils::parseDoubles ( const std::string &  doubleString )

inline

Converts a string to a set of doubles.

Parameters

doubleString

String containing doubles.

Returns

Set of doubles. If no valid double was found the empty set is returned.

parseNumberSet()

std::unique_ptr< autopas::NumberSet< double > > autopas::utils::StringUtils::parseNumberSet ( const std::string &  setString )

inline

Converts a string to a NumberSet<double>.

Note

Formats: NumberSetFinite [x,y,z] NumberInterval x-y

Parameters

setString

String containing the set.

Returns

NumberSet<double>. If no valid double was found the empty set is returned.

tokenize()

std::vector< std::string > autopas::utils::StringUtils::tokenize ( const std::string &  searchString, const std::string &  delimiters  )

inline

Splits a string by multiple delimiters.

Parameters

searchString
delimiters

Returns

Set of substrings.

Variable Documentation

regexDoubleStr

const std::string autopas::utils::StringUtils::regexDoubleStr

static

Initial value:

{
    "[0-9]+"  
    "\\.?"    
    "[0-9]*"  
    "(?:"     
    "e"       
    "-?"      
    "[0-9]+"  
    ")?"      
}

Regex for a double e.g.

1 | 1.2 | 1.2e-3
