Directory::Directory (  )

Description: Initiate the instance to a know but invalid state. The instance must be successfully initialized with one of the SetTo() members before it can be used. Author: Kurt Skauen (kurt@atheos.cx)

Directory::Directory (  const std::string & cPath, int nOpenMode = O_RDONLY )

Description: See: SetTo( const std::string& cPath, int nOpenMode ) Author: Kurt Skauen (kurt@atheos.cx)

Directory::Directory (  const Directory & cDir, const std::string & cPath, int nOpenMode = O_RDONLY )

Description: See: ( const Directory& cDir, const std::string& cPath, int nOpenMode ) Author: Kurt Skauen (kurt@atheos.cx)

Directory::Directory (  const FileReference & cRef, int nOpenMode = O_RDONLY )

Description: See: SetTo( const FileReference& cRef, int nOpenMode ) Author: Kurt Skauen (kurt@atheos.cx)

Directory::Directory (  const FSNode & cNode )

Description: See: SetTo( const FSNode& cNode ) Author: Kurt Skauen (kurt@atheos.cx)

Directory::Directory (  const Directory & cDir )

Description: Make a independent copy of another directory. The new directory will consume a new file descriptor so the copy might fail (throwing an errno_exception exception) if the process run out of file descriptors. Parameters: cDir   The directory to copy Author: Kurt Skauen (kurt@atheos.cx)
