Alzabo::Runtime::RowCursor - Cursor that returns
my $cursor = $schema->table('foo')->all_rows;
while ( my $row = $cursor->next )
print $row->select('foo'), "\n";
Objects in this class are used to return
"Alzabo::Runtime::Row" 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 RATIONALE FOR
CURSORS section in Alzabo::Design.
Returns the next "Alzabo::Runtime::Row" object
or undef if no more are available.
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 "next" twice, calling all_rows
after it will only return three.
Resets the cursor so that the next "next" call
will return the first row of the set.
Returns the number of rows returned by the cursor so far.
Return the next row in a hash, where the hash key is the table name and the hash
value is the row object.
