		const css::uno::Reference< css::i18n::XBreakIterator > &	rBI,
		const css::lang::Locale &	rLocale
	)

Compares two strings using natural order.

For non digit characters, the comparison use the same algorithm as rtl_str_compare. When a number is encountered during the comparison, natural order is used. Thus, Heading 10 will be considered as greater than Heading 2. Numerical comparison is done using decimal representation.

Beware that "MyString 001" and "MyString 1" will be considered as equal since leading 0 are meaningless.

Parameters

str	the object to be compared.

Returns

0 - if both strings are equal < 0 - if this string is less than the string argument > 0 - if this string is greater than the string argument

COMPHELPER_DLLPUBLIC OUString comphelper::string::convertCommaSeparated

(

css::uno::Sequence< OUString > const &

i_rSeq

)

Convert a sequence of strings to a single comma separated string.

Note that no escaping of commas or anything fancy is done.

Parameters

i_rSeq

A list of strings to be concatenated.

Returns

A single string containing the concatenation of the given list, interspersed with the string ", ".

COMPHELPER_DLLPUBLIC css::uno::Sequence< OUString > comphelper::string::convertCommaSeparated

Convert a single comma separated string to a sequence of strings.

Note that no escaping of commas or anything fancy is done.

Parameters

i_rString

A string containing comma-separated words.

Returns

A sequence of strings resulting from splitting the given string at ',' tokens and stripping whitespace.

COMPHELPER_DLLPUBLIC sal_uInt32 comphelper::string::decimalStringToNumber

(

OUString const &

str

)

Convert a decimal string to a number.

The string must be base-10, no sign but can contain any codepoint listed in the "Number, Decimal Digit" Unicode category.

No verification is made about the validity of the string, passing string not containing decimal digit code points gives unspecified results

If your string is guaranteed to contain only ASCII digit use OUString::toInt32 instead.

Parameters

str	The string to convert containing only decimal digit codepoints.

Returns

The value of the string as an int32.
