class c4_Cursor

An iterator for collections of rows (views).

Public members
	c4_Cursor (c4_Sequence& implementation_, int index_); Construct a new cursor
c4_RowRef	operator* () const; Dereference this cursor to "almost" a row
c4_RowRef	operator[] (int index_) const; This is the same as *(cursor + offset)
c4_Cursor&	operator++ (); Pre-increment the cursor
c4_Cursor	operator++ (int); Post-increment the cursor
c4_Cursor&	operator-- (); Pre-decrement the cursor
c4_Cursor	operator-- (int); Post-decrement the cursor
c4_Cursor&	operator+= (int offset_); Advance by a given offset
c4_Cursor&	operator-= (int offset_); Back up by a given offset
c4_Cursor	operator- (int) const; Subtract a specified offset
int	operator- (c4_Cursor cursor_) const; Return the distance between two cursors

Friends
friend c4_Cursor	operator+ (c4_Cursor cursor_, int offset_); Add specified offset
friend c4_Cursor	operator+ (int offset_, c4_Cursor cursor_); Add specified offset to cursor
friend bool	operator== (c4_Cursor a_, c4_Cursor b_); Return true if both cursors are equal
friend bool	operator!= (c4_Cursor a_, c4_Cursor b_); Return true if both cursors are not equal
