## 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 | ( | char16 * | buffer,
|  | int32 | size
| ) |  |
| inline

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

## Member Function Documentation

int32 getSize | ( |  | ) | const
| inline

returns buffer size

operator const char16 * | ( |  | ) | const
| inline

cast to char16*

int32 getLength | ( |  | ) | const

Returns length of string (in code unit).

Note this is not the count of character!

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

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

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

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

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

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

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

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

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

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

Copy to ASCII string.

bool scanInt | ( | int64 & | value | ) | const

Scan integer from string.

bool printInt | ( | int64 | value | ) |

Print integer to string.

bool scanFloat | ( | double & | value | ) | const

Scan float from string.

bool printFloat | ( | double | value,
|  | int32 | precision = `4`
| ) |  |

Print float to string.
