Constructor & Destructor Documentation

UString::UString (  ) 

Constructs a null string.

Definition at line 266 of file ustring.cpp.

UString::UString ( char  c  )  [explicit]

Constructs a string from the single character c.

Definition at line 272 of file ustring.cpp.

UString::UString ( const char *  c  ) 

Constructs a string from a classical zero determined char string.

Definition at line 279 of file ustring.cpp.

UString::UString ( const UChar c,
int  length 
)

Constructs a string from an array of Unicode characters of the specified length.

Definition at line 296 of file ustring.cpp.

UString::UString ( UChar c,
int  length,
bool  copy 
)

If copy is false the string data will be adopted.

That means that the data will NOT be copied and the pointer will be deleted when the UString object is modified or destroyed. Behaviour defaults to a deep copy if copy is true.

Definition at line 307 of file ustring.cpp.

KJS::UString::UString ( const UString s  )  [inline]

Copy constructor.

Makes a shallow copy only.

Definition at line 256 of file ustring.h.

KJS::UString::UString ( const QString  ) 

Convenience declaration only ! You'll be on your own to write the implementation for a construction from QString.

Note: feel free to contact me if you want to see a dummy header for your favorite FooString class here !

KJS::UString::UString ( const DOM::DOMString &   ) 

Convenience declaration only ! See UString(const QString&).

UString::UString ( const UString ,
const UString  
)

Concatenation constructor.

Makes operator+ more efficient.

Definition at line 322 of file ustring.cpp.

KJS::UString::~UString (  )  [inline]

Destructor.

If this handle was the only one holding a reference to the string the data will be freed.

Definition at line 277 of file ustring.h.


Member Function Documentation

UString & UString::append ( const UString  ) 

Append another string.

Definition at line 454 of file ustring.cpp.

char * UString::ascii (  )  const

Convert the Unicode string to plain ASCII chars chopping of any higher bytes.

This method should only be used for *debugging* purposes as it is neither Unicode safe nor free from side effects. In order not to waste any memory the char buffer is static and *shared* by all UString instances.

Definition at line 482 of file ustring.cpp.

CString UString::cstring (  )  const

Returns:
The string converted to the 8-bit string type CString().

Definition at line 477 of file ustring.cpp.

const UChar* KJS::UString::data (  )  const [inline]

Returns:
A pointer to the internal Unicode data.

Definition at line 339 of file ustring.h.

int UString::find ( const UString f,
int  pos = 0 
) const

Returns:
Position of first occurrence of f starting at position pos. -1 if the search was not successful.

Definition at line 795 of file ustring.cpp.

UString UString::from ( double  d  )  [static]

Constructs a string from a double.

Definition at line 386 of file ustring.cpp.

UString UString::from ( long  l  )  [static]

Constructs a string from a long.

Definition at line 360 of file ustring.cpp.

UString UString::from ( unsigned int  u  )  [static]

Constructs a string from an unsigned int.

Definition at line 342 of file ustring.cpp.

UString UString::from ( int  i  )  [static]

Constructs a string from an int.

Definition at line 337 of file ustring.cpp.

bool UString::is8Bit (  )  const

Use this if you want to make sure that this string is a plain ASCII string.

For example, if you don't want to lose any information when using cstring() or ascii().

Returns:
True if the string doesn't contain any non-ASCII characters.

Definition at line 546 of file ustring.cpp.

bool KJS::UString::isEmpty (  )  const [inline]

Returns:
True if null or zero length.

Definition at line 347 of file ustring.h.

bool KJS::UString::isNull (  )  const [inline]

Returns:
True if null.

Definition at line 343 of file ustring.h.

UString& KJS::UString::operator+= ( const UString s  )  [inline]

Appends the specified string.

Definition at line 334 of file ustring.h.

UString & UString::operator= ( const char *  c  ) 

Assignment operator.

Definition at line 519 of file ustring.cpp.

UCharReference UString::operator[] ( int  pos  ) 

Writable reference to character at specified position.

Definition at line 567 of file ustring.cpp.

UChar UString::operator[] ( int  pos  )  const

Const character at specified position.

Definition at line 559 of file ustring.cpp.

QConstString KJS::UString::qconststring (  )  const

QString KJS::UString::qstring (  )  const

int UString::rfind ( const UString f,
int  pos 
) const

Returns:
Position of first occurrence of f searching backwards from position pos. -1 if the search was not successful.

Definition at line 829 of file ustring.cpp.

int KJS::UString::size (  )  const [inline]

Returns:
The length of the string.

Definition at line 359 of file ustring.h.

DOM::DOMString KJS::UString::string (  )  const

UString UString::substr ( int  pos = 0,
int  len = -1 
) const

Returns:
The sub string starting at position pos and length len.

Definition at line 865 of file ustring.cpp.

unsigned UString::toArrayIndex ( bool *  ok = 0  )  const

Attempts an conversion to an array index.

The "ok" boolean will be set to true if it is a valid array index according to the rule from ECMA 15.2 about what an array index is. It must exactly match the string form of an unsigned integer, and be less than 2^32 - 1.

Definition at line 787 of file ustring.cpp.

double UString::toDouble ( bool  tolerateTrailingJunk,
bool  tolerateEmptyString 
) const

Attempts an conversion to a number.

Apart from floating point numbers, the algorithm will recognize hexadecimal representations (as indicated by a 0x or 0X prefix) and +/- Infinity. Returns NaN if the conversion failed.

Parameters:
tolerateTrailingJunk if true, toDouble can tolerate garbage after the number.
tolerateEmptyString if false, toDouble will turn an empty string into NaN rather than 0.

Definition at line 604 of file ustring.cpp.

UString UString::toLower (  )  const

Returns this string converted to lower case characters.

Definition at line 703 of file ustring.cpp.

unsigned long UString::toULong ( bool *  ok,
bool  tolerateEmptyString 
) const

Attempts an conversion to an unsigned long integer.

ok will be set according to the success. @param ok make this point to a bool in case you need to know whether the conversion succeeded.

Parameters:
tolerateEmptyString if false, toULong will return false for *ok for an empty string.

Definition at line 682 of file ustring.cpp.

UString UString::toUpper (  )  const

Returns this string converted to upper case characters.

Definition at line 711 of file ustring.cpp.
