GBaseString Class Reference

Inheritance diagram for GBaseString:

GP< GStringRep > GPBase GNativeString GUTF8String

List of all members.

Detailed Description

General purpose character string. Each dirivied instance of class GBaseString# represents a character string. Overloaded operators provide a value semantic to GBaseString# objects. Conversion operators and constructors transparently convert between GBaseString# objects and const char*# pointers. The GBaseString# class has no public constructors, since a dirived type should always be used to specify the desired multibyte character encoding.

Functions taking strings as arguments should declare their arguments as "#const char*#". Such functions will work equally well with dirived GBaseString# objects since there is a fast conversion operator from the dirivied GBaseString# objects to "#const char*#". Functions returning strings should return GUTF8String# or GNativeString# objects because the class will automatically manage the necessary memory.

Characters in the string can be identified by their position. The first character of a string is numbered zero. Negative positions represent characters relative to the end of the string (i.e. position #-1# accesses the last character of the string, position #-2# represents the second last character, etc.)
