10DBIx::Class::Cursor - Abstract object representing a query cursor on a
11resultset.
12
13=head1 SYNOPSIS
14
15 my $cursor = $schema->resultset('CD')->cursor();
16 my $first_cd = $cursor->next;
17
18=head1 DESCRIPTION
19
20A Cursor represents a query cursor on a L<DBIx::Class::ResultSet> object. It
21allows for traversing the result set with L</next>, retrieving all results with
22L</all> and resetting the cursor with L</reset>.
23
24Usually, you would use the cursor methods built into L<DBIx::Class::ResultSet>
25to traverse it. See L<DBIx::Class::ResultSet/next>,
26L<DBIx::Class::ResultSet/reset> and L<DBIx::Class::ResultSet/all> for more
27information.
