## 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.
