.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Objects in this class are used to return
\&\f(CW\*(C`Alzabo::Runtime::Row\*(C'\fR objects for queries.
The cursor does not preload objects but creates them on demand, which
is much more efficient.  For more details on the rational please see
the \s-1RATIONALE FOR CURSORS\s0 section in
Alzabo::Design.

.SS "next"
.IX Subsection "next"
Returns the next \f(CW\*(C`Alzabo::Runtime::Row\*(C'\fR
object or undef if no more are available.
.SS "all_rows"
.IX Subsection "all_rows"
Returns all the rows available from the current point onwards.  This
means that if there are five rows that will be returned when the
object is created and you call \f(CW\*(C`next\*(C'\fR twice, calling all_rows
after it will only return three.
.SS "reset"
.IX Subsection "reset"
Resets the cursor so that the next \f(CW\*(C`next\*(C'\fR call will
return the first row of the set.
.SS "count"
.IX Subsection "count"
Returns the number of rows returned by the cursor so far.
.SS "next_as_hash"
.IX Subsection "next_as_hash"
Return the next row in a hash, where the hash key is the table name
and the hash value is the row object.
