// 					Class Specification : COXUNC
// ==========================================================================

// Header file : OXUNC.h

// Version: 9.3

// //////////////////////////////////////////////////////////////////////////

// Properties:
//	NO	Abstract class (does not have any objects)
//	YES	Derived from CObject

//	NO	Is a Cwnd.                     
//	NO	Two stage creation (constructor & Create())
//	NO	Has a message map
//	NO	Needs a resource (template)

//	NO	Persistent objects (saveable on disk)      
//	NO	Uses exceptions

// //////////////////////////////////////////////////////////////////////////

// Desciption :         
//	This class encapsulates a full path specification
//	A COXUNC object can have three different forms
//		- Strict UNC : \\Server\Share\Directory\File.ext
//		- Local path : C:\Directory\File.ext
//		- URL part : www.dundas.com/directory/file.ext

//	A UNC must always start with a double slash
//	A URL must be explicitly marked as URL part (URLPart())
//	Other COXUNC objects or local paths

//	To put a directory in a COXUNC object let it end in a (back)slash
//	E.g. C:\Temp\ is a directory
//		 C:\Test is a file

// Remark:
//	This class makes no differences between a slash "/" and a backslash "\"

//	If a directory is specified it always ends in a (back)slash
//	If the directory is absolute it also starts with a (back)slash

//	All public functions which do not start with a verb access only
//	 the internal structure of the object and do not perform an action
//	 on the actual file system (like rename, delete etc.)

//	Two conversion operators that were present in a previous version of this class
//   have been replaced by an explicit function call
//	operator const CString() const;		-> const CString Full() const;
//	operator CString&();				-> CString& Full();

// Prerequisites (necessary conditions):
