Alzabo::Runtime::RowCursor(3pm) User Contributed Perl Documentation Alzabo::Runtime::RowCursor(3pm)NAME
Alzabo::Runtime::RowCursor - Cursor that returns "Alzabo::Runtime::Row" objects
SYNOPSIS
use Alzabo::Runtime::RowCursor;
my $cursor = $schema->table('foo')->all_rows;
while ( my $row = $cursor->next )
{
print $row->select('foo'), "
";
}
DESCRIPTION
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.
INHERITS FROM
"Alzabo::Runtime::Cursor"
METHODS
next
Returns the next "Alzabo::Runtime::Row" object or undef if no more are available.
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 "next" twice, calling all_rows after it will only return three.
reset
Resets the cursor so that the next "next" call will return the first row of the set.
count
Returns the number of rows returned by the cursor so far.
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.
