split() [1/2]

bool split	(	const char	splitter,
		std::vector< String > &	substrings,
		bool	quote_protect = false
	)		const

Splits a string into substrings using splitter as delimiter.

If splitter is not found, the whole string is put into substrings. If splitter is empty, the string is split into individual characters. If the invoking string is empty, substrings will also be empty.

quote_protect (default: false) can be used to split only between quoted blocks e.g. ' "a string" , "another string with , in it" ' results in only two substrings (with double quotation marks removed). Every returned substring is trimmed and then (if present) has surrounding quotation marks removed.

Returns

true if one or more splits occurred, false otherwise

concatenate().

split() [2/2]

bool split	(	const String &	splitter,
		std::vector< String > &	substrings
	)		const

Splits a string into substrings using splitter (the whole string) as delimiter.

If splitter is not found, the whole string is put into substrings. If splitter is empty, the string is split into individual characters. If the invoking string is empty, substrings will also be empty.

Returns

true if one or more splits occurred, false otherwise

See also

concatenate().

split_quoted()

bool split_quoted	(	const String &	splitter,
		std::vector< String > &	substrings,
		char	q = '"',
		QuotingMethod	method = ESCAPE
	)		const

Splits a string into substrings using splitter (the whole string) as delimiter, but does not split within quoted substrings.

A "quoted substring" has the format as produced by quote(q, method), where q is the quoting character and method defines the handling of embedded quotes. Substrings will not be "unquoted" or otherwise processed.

If splitter is not found, the whole string is put into substrings. If splitter or the invoking string is empty, substrings will also be empty.

Returns

true if one or more splits occurred, false otherwise

Exceptions

Exception::ConversionError

is thrown if quotation marks are not balanced

See also

concatenate(), quote().

substitute() [1/2]

String& substitute	(	char	from,

Referenced by MascotGenericFile::getNextSpectrum_(), XFDRAlgorithm::isSameProtein_(), OpenMS::StringUtils::quote(), OpenMS::StringUtils::unquote(), and XMLHandler::writeXMLEscape().

substitute() [2/2]

String& substitute	(	const String &	from,
		const String &	to
	)

Replaces all occurrences of the string from by the string to.

substr()

String substr	(	size_t	pos = 0,
		size_t	n = npos
	)		const

Wrapper for the STL substr() method. Returns a String object with its contents initialized to a substring of the current object.

Parameters

pos

Position of a character in the current string object to be used as starting character for the substring. If the pos is past the end of the string, it is set to the end of the string.

n

Length of the substring. If this value would make the substring to span past the end of the current string content, only those characters until the end of the string are used. npos is a static member constant value with the greatest possible value for an element of type size_t, therefore, when this value is used, all the characters between pos and the end of the string are used as the initialization substring.
