<html><head><base target=k-main></head><body bgcolor=white> <font face=Times size=3> Row references are created when dereferencing a <A HREF="c4_Cursor.html" >c4_Cursor</A> or when indexing an element of a <A HREF="c4_View.html" >c4_View</A>. Assignment will change the corresponding item. Rows (objects of type <A HREF="c4_Row.html" >c4_Row</A>) are a special case of row references, consisting of a view with exactly one item. <P> Internally, row references are very similar to cursors, in fact they are little more than a wrapper around them. The essential difference is one of semantics: comparing row references compares contents, copying row references copies the contents, whereas cursor comparison and copying deals with the pointer to the row, not its contents. <P> <hr size=1> <dl> <if !private> <a name="c4_RowRef_Container___const"><dt> <nobr> <A HREF="c4_View.html" >c4_View</A> <b>Container</b> () <i>const</i>; </nobr> <dd> <font face=Helvetica size=-1>Return the underlying container view</font> <p> <if !private> <a name="c4_RowRef__cursor"><dt> <nobr> <A HREF="c4_Cursor.html" >c4_Cursor</A> <b>_cursor</b>; </nobr> <dd> <font face=Helvetica size=-1></font> <p> <if !private> <a name="c4_RowRef_c4_RowRef_c4_Cursor_"><dt> <nobr> <b>c4_RowRef</b> (<A HREF="c4_Cursor.html" >c4_Cursor</A>); </nobr> <dd> <font face=Helvetica size=-1>Constructor, not for general use</font> <p> <if !private> <a name="c4_RowRef_operator_____const"><dt> <nobr> <A HREF="c4_Cursor.html" >c4_Cursor</A> <b>operator& </b> () <i>const</i>; </nobr> <dd> <font face=Helvetica size=-1>Return the cursor associated to this row</font> <p> <if !private> <a name="c4_RowRef_operator___const__"><dt> <nobr> <A HREF="c4_RowRef.html" >c4_RowRef</A> <b>operator= </b> (const <A HREF="c4_RowRef.html" >c4_RowRef</A>& row_); </nobr> <dd> <font face=Helvetica size=-1>Assign the value of another row to this one</font> <p> </dl> <hr size=1 width=50 align=left> class <b>c4_RowRef</b> </font> </body></html>
