Detailed Description

String class used within the GUI system.

For the most part, this class can replace std::string in basic usage. However, currently String does not use the current locale, and also comparisons do not take into account the Unicode data tables, so are not 'correct' as such.

Constructor & Destructor Documentation

CEGUI::String::String ( const String str)
inline

Copy constructor - Creates a new string with the same value as str.

Parameters
strString object used to initialise the newly created string
Returns
Nothing
CEGUI::String::String ( const String str,
size_type  str_idx,
size_type  str_num = npos 
)
inline

Constructs a new string initialised with code points from another String object.

Parameters
strString object used to initialise the newly created string
str_idxStarting code-point of str to be used when initialising the new String
str_numMaximum number of code points from str that are to be assigned to the new String
Returns
Nothing
CEGUI::String::String ( const std::string &  std_str)
inline

Constructs a new string and initialises it using the std::string std_str.

Parameters
std_strThe std::string object that is to be used to initialise the new String object.
Note
The characters of std_str are taken to be unencoded data which represent Unicode code points 0x00..0xFF. No translation of the provided data will occur.
Returns
Nothing
Exceptions
std::length_errorThrown if resulting String object would be too big.
CEGUI::String::String ( const std::string &  std_str,
size_type  str_idx,
size_type  str_num = npos 
)
inline

Constructs a new string initialised with characters from the given std::string object.

Parameters
std_strstd::string object used to initialise the newly created string
str_idxStarting character of std_str to be used when initialising the new String
Note
The characters of std_str are taken to be unencoded data which represent Unicode code points 0x00..0xFF. No translation of the provided data will occur.
Parameters
str_numMaximum number of characters from std_str that are to be assigned to the new String
Returns
Nothing
Exceptions
std::length_errorThrown if resulting String object would be too big.
CEGUI::String::String ( const utf8 *  utf8_str)
inline

Constructs a new String object and initialise it using the provided utf8 encoded string buffer.

Parameters
utf8_strPointer to a buffer containing a null-terminated Unicode string encoded as utf8 data.
Note
A basic string literal (cast to utf8*) can be passed to this function, provided that the string is comprised only of code points 0x00..0x7f. The use of extended ASCII characters (with values >0x7f) would result in incorrect behaviour as the String will attempt to 'decode' the data, with unpredictable results.
Returns
Nothing
Exceptions
std::length_errorThrown if resulting String object would be too big.
CEGUI::String::String ( const utf8 *  utf8_str,
size_type  chars_len 
)
inline

Constructs a new String object and initialise it using the provided utf8 encoded string buffer.

    A basic string literal (cast to utf8*) can be passed to this function, provided that the string is
    comprised only of code points 0x00..0x7f.  The use of extended ASCII characters (with values >0x7f)
    would result in incorrect behaviour as the String will attempt to 'decode' the data, with unpredictable
    results.
Parameters
utf8_strPointer to a buffer containing Unicode string data encoded as utf8.
Note
A basic string literal (cast to utf8*) can be passed to this function, provided that the string is comprised only of code points 0x00..0x7f. The use of extended ASCII characters (with values >0x7f) would result in incorrect behaviour as the String will attempt to 'decode' the data, with unpredictable results.
Parameters
chars_lenLength of the provided utf8 string in code units (not code-points).
Returns
Nothing
Exceptions
std::length_errorThrown if resulting String object would be too big.

CEGUI::String::String ( const char *  cstr)
inline
