NAME

DBIx::Class::Storage::DBI::Cursor - 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.
