class String : public Moveable<String, AString<String0> > 

String is a value class that contains an array of characters (or bytes). It is designed to have fast copy operations. The array of characters is zero terminated. String provides non-mutable access to the array of characters. String can store 8 bit encoded string or an UTF-8 encoded string. For UTF-8 strings, however, String works with raw 8 bit values - there are not automatic conversions performed e.g. in operator[]. If you need to access individual UTF-8 characters, the best practice in most cases is to convert it to WString (and eventually back after processing).

String is also often used to store raw binary data.

WString is similar to String, but it uses 16 bit Ucs2 encoding. String and WString share a number of common functions through the AString interface.

Default constructor. Constructs empty String.

Default copy constructor.

Creates a copy of zero terminated string s.

Constructs a string equal to first n characters of string s. Zero characters are included.

Constructs a string equal to first n characters of String s.  Zero characters are included.

String(const byte *s, int n)

Constructs a string equal to first n bytes of s. Zero characters are included.

Constructs a string equal to first lim - s characters of s. Zero characters are included.

Constructs a string consisting of count characters equal to chr. chr can be zero.

String(StringBuffer& b)

Constructs a string from b. b is emptied by this operation.

String(const Nuller&)

Constructs empty String. This variant is important to allow assigning Null to String (which is same as assigning the empty String).

Constructor to achieve minimal STL compatibility.

Reduces memory used by string to minimum (size optimization).

Returns a number of characters contained in String. This is equal GetCount() if default charset is not UTF-8, but different for UTF-8. It is faster equivalent of ToWString().GetCount().

WString ToWString() const

Convert String to WString using current default character set.

const String& ToString() const

Returns *this. Useful because ToString is standard method to convert concrete type to text, used by AsString template (and therefore by operator << as well).

static String GetVoid()

Returns special Void value. This value is same as empty string, but IsVoid method returns true for it. It can be used in special scenarios where client code needs to distinguish between two empty values (let us say Void is "more empty"...). For example, LoadFile returns Void string if file failed to load, but normal empty string if it is empty.

Returns true if String is special value returned by GetVoid.

bool IsEqual(const String& s) const

Return true if string is equal to s.

int Compare(const String0& s) const

Lexicographic comparison, return -1 if this string is lower, 0 for equality, 1 if this string is greater. Individual characters are compared as unsigned integer values.

Returns the hash value of the string.

const String& operator+=(char c)

Appends single character c. This operations has constant amortized time (in other words, internal space used by implementation grows exponentially, like with Vector or std::vector). c can be zero.

Appends len characters from string s (s can contain zero characters).

Replace character at position i with chr.

Sets the number of characters (length) to pos.

Returns a pointer to the first character.

Returns a pointer to ending zero.

Removes count element starting at position pos.

Empties the string.

Returns the number of characters.

Returns the number of allocated characters (maximum string length before it has to grow)

Reserves r characters of internal storage for future concatenation operations.

const String& operator+=(const char *s)

const String& operator+=(const String& s)

Appends a zero terminated string s.

String& operator=(const String& s)

Assigns another string s. This operations is relatively fast and does not depend on the length of string.

String& operator=(const char *s)

Assign a zero terminated string s.

String& operator=(StringBuffer& b)

Assigns the content of StringBuffer. After the operation,b is emptied.

String& operator<<=(const String& s)

"Deep" assignment. It is equivalent of standard assignment followed by Shrink operation (in other words, internal buffer gets reallocated to the exact size of source).

Conversion for minimal STL compatibility.

Returns Begin().

Returns the character at position i.

class WString : public Moveable<WString, AString<WString0> > 

WString is similar to String, but it uses 16 bit Ucs2 encoding. String and WString share a number of common functions through the AString interface.

Default constructor. Constructs empty WString.

Default copy constructor.

WString(const wchar *s)

Creates a copy of zero terminated string s.

Creates a copy of zero terminated string s.

Constructs a string equal to first n characters of WString s (s can contain zero characters).

WString(const wchar *s, int n)

Constructs a string equal to first n characters of s (s can contain zero characters).

WString(const wchar *s, const wchar *lim)

Constructs a string equal to first lim - s characters of s (s can contain zero characters).

Constructs a string equal to first n characters of zero terminated string s (s can contain zero characters).

Constructs a string equal to first n characters of zero terminated string s (s can contain zero characters).

Constructs a string consisting of count characters equal to chr. chr can be zero.

WString(WStringBuffer& b)

Constructs a string from b. b is emptied by this operation.

WString(const Nuller&)

Constructs empty WString. This variant is important to allow assigning Null to WString (which is same as assigning the empty WString).

Constructor to achieve minimal STL compatibility.

Reduces memory used by string to minimum (size optimization).

String ToString() const

Converts WString to String using current default character set. Also serves as standard text conversion (for AsString and operator<< templates).

static WString GetVoid()

Returns special Void value. This value is same as empty string, but IsVoid method returns true for it. It can be used in special scenarios where client code needs to distinguish between two empty values (let us say Void is "more empty"...). For example, LoadFile returns Void string if file failed to load, but normal empty string if it is empty.

Returns true if String is special value returned by GetVoid.

const wchar *Begin() const

Returns a pointer to the first character.

const wchar *End() const

Returns a pointer to ending zero.

Returns the number of characters.

Returns the number of allocated characters (maximum string length before it has to grow)

Appends single character c. This operations has constant amortized time (in other words, internal space used by implementation grows exponentially, like with Vector or std::vector).

void Cat(const wchar *s, int length)

Appends len characters from string s (s can contain zero characters).

Returns the hash value of the string.

bool IsEqual(const WString& s) const

Return true if string is equal to s.

int Compare(const WString& s) const

Lexicographic comparison, return -1 if this string is lower, 0 for equality, 1 if this string is greater. Individual characters are compared as unsigned integer values.

void Insert(int pos, const wchar *s, int count)

Empties the string.

Replace character at position pos  with ch.

Sets the number of characters (length) to pos.

A class that implements behavior common to both String and WString.

Clears the content of the string.

Return true if the length of the string is zero.

const tchar *End() const

Returns a pointer to the end of the string.

const tchar *Last() const

Returns a pointer to the last character in the string.

const tchar *GetIter(int i) const

void Insert(int pos, const tchar *s, int count)

void Insert(int pos, const String& s)
