Detailed Description

A basic string class made of chars.

Member Function Documentation

clear()

void nctl::String::clear

(

)

Clears the string.

Note

Length will be reset to zero but capacity remains unmodified.

operator=()

String & nctl::String::operator=

(

const String &

other

)

Assignment operator (it might extend or truncate the original text)

Note

Not implemented with the copy-and-swap idiom because it has to copy data.

replace()

unsigned int nctl::String::replace	(	const String &	source,
		unsigned int	srcChar,
		unsigned int	numChar,
		unsigned int	destChar
	)

Replaces characters from somewhere in the other string to somewhere in this one (no truncation)

The method returns the number of characters copied, to allow truncation.

setLength()

unsigned int nctl::String::setLength

(

unsigned int

newLength

)

Sets the string length.

The method is useful to update the string length after writing into it through the data() pointer.

utf8ToCodePoint() [1/2]

int nctl::String::utf8ToCodePoint	(	unsigned int	position,
		unsigned int &	codePoint
	)		const

Retrieves the Unicode code point from the UTF-8 substring starting at the specified position.

Returns

The number of code units used by UTF-8 to encode the Unicode code point

utf8ToCodePoint() [2/2]

int nctl::String::utf8ToCodePoint	(	unsigned int	position,
		unsigned int &	codePoint,
		unsigned int *	codeUnits
	)		const

Retrieves the Unicode code point and the UTF-8 code units from the UTF-8 substring starting at the specified position.

Returns

The number of code units used by UTF-8 to encode the Unicode code point
