Class::DBI::Iterator(3User Contributed Perl DocumentatiClass::DBI::Iterator(3)NAMEClass::DBI::Iterator - Iterate over Class::DBI search results
SYNOPSIS
my $it = My::Class->search(foo => 'bar');
my $results = $it->count;
my $first_result = $it->first;
while ($it->next) { ... }
my @slice = $it->slice(10,19);
my $slice = $it->slice(10,19);
$it->reset;
$it->delete_all;
DESCRIPTION
Any Class::DBI search (including a has_many method) which returns
multiple objects can be made to return an iterator instead simply by
executing the search in scalar context.
Then, rather than having to fetch all the results at the same time, you
can fetch them one at a time, potentially saving a considerable amount
of processing time and memory.
CAVEAT
Note that there is no provision for the data changing (or even being
deleted) in the database inbetween performing the search and retrieving
the next result.
