NAME
DBIx::Class::Cursor - Abstract object representing a query cursor on a resultset.SYNOPSIS
my $cursor = $schema->resultset('CD')->cursor(); my $first_cd = $cursor->next;
DESCRIPTION
A Cursor represents a query cursor on a DBIx::Class::ResultSet object. It allows for traversing the result set with ``next'', retrieving all results with ``all'' and resetting the cursor with ``reset''.Usually, you would use the cursor methods built into DBIx::Class::ResultSet to traverse it. See ``next'' in DBIx::Class::ResultSet, ``reset'' in DBIx::Class::ResultSet and ``all'' in DBIx::Class::ResultSet for more information.
METHODS

reset
Virtual method. Resets the cursor to the beginning.
