Detailed Description

Class for smart character strings.

The class SbString provides functions to manage strings of Latin-1 (ASCII) or Unicode characters.

About Unicode:

For more information about the Unicode standard, see http://unicode.org

On Microsoft Windows platforms the Unicode string is stored in utf16, while on Unix/Linux based systems (including MacOSX) it uses utf32. In order to get the best performance the user should use Latin1 functions or WideChar functions.
On Microsoft Windows platforms there is no difference between WideChars and Utf16 because these platforms use Utf16.
On Unix platforms converting between utf16 and WideChars is not free and the user should try to use wide chars as much as possible.
Nokia's Qt toolkit uses Utf16 as internal storage, so to convert a string from or to a QString use the toUtf16 and fromUtf16 functions.
All access to files on the system should be done using the class SbFileHelper which supports Unicode file names.

About SO_WCHAR_T:

This macro was introduced in order to have generic code across Windows and Linux platforms. Because on Linux platforms wchar_t doesn't have the same type as on the Windows platform, it was decided to add this macro to keep a common size on both systems.

Since OpenInventor 8.0 there are separate functions and it is possible to use functions, on both systems, which use the same data size. Most of the time it's better to use utf16 functions when the size of the characters must be constant whatever is the platform.

SO_WCHAR_T is now deprecated and should not be used except for specific issues.

About locales:

In order to read values in IV files the initClass function overwrites some locales using the setlocales function provided by the standard lib C. Setting the locale after the init of OpenInventor can break reading IV files.

String manipulation:

Since OpenInventor 8.0 SbString has many new functions for string manipulation including:

New functions to convert strings to numbers.
New functions to convert numbers to strings.
Find functions to find sub-strings within a string.
SbString now supports "null" strings (note this is not the same as an empty string).
SbStringList::split() splits a string based on a specified separator character.

EXAMPLE

1) Construction of a string from a regular Latin-1/Ascii C string.

SbString s = "This is my string.";
or
SbString s = SbString().fromLatin1( "This is my string." );
or
SbString s( "This is my string." );

2) Construction of a string from a WideChar string (wchar_t string).

SbString s = L"This is my WideChar string";
or
SbString s = SbString().fromWideChar( L"This is my string." );
or
SbString s = SbString( myStdWString );

3) Conversion SbString <-> QString

To set an SbString from a QString:
SbString s = SbString().fromUtf16( qStr.utf16() );

SbString::fromUtf16
SbString & fromUtf16(const unsigned short *str)
Set the string from a UTF-16 string.
To set a QString from an SbString:
QString s = QString::fromUtf16( sbStr.toUtf16() );

4) Find/Contains examples:

SbString( "This is my string" ).contains( "Hello" ) // returns false.
 
SbString( "This is my string" ).contains( "my" ) // returns true.
 
SbString( "This is my string" ).containsAny( "aze" ) // returns false.
 
SbString( "This is my string" ).containsAny( "Tzw" ) // returns true.
 
SbString( "This is my string" ).find( "Zoo" ) // returns SbString::npos.
 
SbString( "This is my string" ).find( "is" ) // returns 2.
 
SbString( "This is my string" ).rfind( "Zoo" ) // returns SbString::npos.
 
SbString( "This is my string" ).rfind( "is" ) // returns 5.
 
SbString( "This is my string" ).findLast( "i" ) // returns 14.
 
SbString( "This is my string" ).findAny( "s" ) // returns 3.

5) Number to string

SbString().setNum( 4, 16 ) // produces the string "0x4".
 
SbString().setNum( 0.5 ) // produces the string "0.5".

6) String to Number

SbString( "5" ).toInt( &result ) // will return 5 and set the result boolean to true.
 
SbString( "aa" ).toInt( &result ) // will return an undefined value and set the result boolean to false.
