1<html><head><base target=k-main></head><body bgcolor=white> 2 3<font face=Times size=3> 4 5Row references are created when dereferencing a <A HREF="c4_Cursor.html" >c4_Cursor</A> or when 6indexing an element of a <A HREF="c4_View.html" >c4_View</A>. Assignment will change the 7corresponding item. Rows (objects of type <A HREF="c4_Row.html" >c4_Row</A>) are a special 8case of row references, consisting of a view with exactly one item. 9<P> 10 11Internally, row references are very similar to cursors, in fact they are 12little more than a wrapper around them. The essential difference is one 13of semantics: comparing row references compares contents, copying row 14references copies the contents, whereas cursor comparison and copying 15deals with the pointer to the row, not its contents. 16 17<P> 18 19 20 21<hr size=1> 22 23<dl> 24 25 <if !private> 26 <a name="c4_RowRef_Container___const"><dt> 27 <nobr> 28 <A HREF="c4_View.html" >c4_View</A> 29 <b>Container</b> () <i>const</i>; 30 </nobr> 31 <dd> 32 33 34 <font face=Helvetica size=-1>Return the underlying container view</font> 35 <p> 36 37 38 <if !private> 39 <a name="c4_RowRef__cursor"><dt> 40 <nobr> 41 <A HREF="c4_Cursor.html" >c4_Cursor</A> 42 <b>_cursor</b>; 43 </nobr> 44 <dd> 45 46 47 <font face=Helvetica size=-1></font> 48 <p> 49 50 51 <if !private> 52 <a name="c4_RowRef_c4_RowRef_c4_Cursor_"><dt> 53 <nobr> 54 55 <b>c4_RowRef</b> (<A HREF="c4_Cursor.html" >c4_Cursor</A>); 56 </nobr> 57 <dd> 58 59 60 <font face=Helvetica size=-1>Constructor, not for general use</font> 61 <p> 62 63 64 <if !private> 65 <a name="c4_RowRef_operator_____const"><dt> 66 <nobr> 67 <A HREF="c4_Cursor.html" >c4_Cursor</A> 68 <b>operator& </b> () <i>const</i>; 69 </nobr> 70 <dd> 71 72 73 <font face=Helvetica size=-1>Return the cursor associated to this row</font> 74 <p> 75 76 77 <if !private> 78 <a name="c4_RowRef_operator___const__"><dt> 79 <nobr> 80 <A HREF="c4_RowRef.html" >c4_RowRef</A> 81 <b>operator= </b> (const <A HREF="c4_RowRef.html" >c4_RowRef</A>& row_); 82 </nobr> 83 <dd> 84 85 86 <font face=Helvetica size=-1>Assign the value of another row to this one</font> 87 <p> 88 89 90</dl> 91 92<hr size=1 width=50 align=left> 93class 94<b>c4_RowRef</b> 95</font> 96 97</body></html> 98
