Detailed Description

UTF-16 string class without buffer management.

Note: that some characters are encoded in 2 UTF16 code units (surrogate pair), this means that getLength returns the number of code unit, not the count of character!

Constructor & Destructor Documentation

UString()

UString ( char16 *  buffer, int32  size  )

inline

Construct from UTF-16 string, size is in code unit (count of char16)

Member Function Documentation

getSize()

int32 getSize ( ) const

inline

returns buffer size

operator const char16 *()

operator const char16 * ( ) const

inline

cast to char16*

getLength()

int32 getLength

(

)

const

Returns length of string (in code unit).

Note this is not the count of character!

assign() [1/2]

UString & assign	(	const char16 *	src,
		int32	srcSize = -1
	)

Copy from UTF-16 buffer (srcSize is in code unit (count of char16)).

append()

UString & append	(	const char16 *	src,
		int32	srcSize = -1
	)

Append UTF-16 buffer (srcSize is in code unit (count of char16)).

copyTo()

const UString & copyTo	(	char16 *	dst,
		int32	dstSize
	)		const

Copy to UTF-16 buffer (dstSize is in code unit (count of char16)).

fromAscii()

UString & fromAscii	(	const char *	src,
		int32	srcSize = -1
	)

Copy from ASCII string (srcSize is in code unit (count of char16)).

assign() [2/2]

UString & assign ( const char *  src, int32  srcSize = -1  )

inline

toAscii()

const UString & toAscii	(	char *	dst,
		int32	dstSize
	)		const

Copy to ASCII string.

scanInt()

bool scanInt

(

int64 &

value

)

const

Scan integer from string.

printInt()

bool printInt

(

int64

value

)

Print integer to string.

scanFloat()

bool scanFloat

(

double &

value

)

const

Scan float from string.

printFloat()

bool printFloat	(	double	value,
		int32	precision = 4
	)

Print float to string.
