=head1 NAME
DBIx::Class::Cursor - Abstract object representing a query cursor on a
resultset.
=head1 SYNOPSIS
my $cursor = $schema->resultset('CD')->cursor();
my $first_cd = $cursor->next;

A Cursor represents a query cursor on a L<DBIx::Class::ResultSet> object. It
allows for traversing the result set with L</next>, retrieving all results with
L</all> and resetting the cursor with L</reset>.
Usually, you would use the cursor methods built into L<DBIx::Class::ResultSet>
to traverse it. See L<DBIx::Class::ResultSet/next>,
L<DBIx::Class::ResultSet/reset> and L<DBIx::Class::ResultSet/all> for more
information.

Virtual method. Returns a new L<DBIx::Class::Cursor> object.
=cut
sub new {
die "Virtual method!";
}
=head2 next
Virtual method. Advances the cursor to the next row.
=cut
sub next {
die "Virtual method!";
}
=head2 reset
Virtual method. Resets the cursor to the beginning.
=cut
sub reset {
die "Virtual method!";
}
=head2 all
Virtual method. Returns all rows in the L<DBIx::Class::ResultSet>.

}
