my ($class, $hashref) = @_;

my $portfolio = {};

if ($hashref->{portfolio_id}) {
($portfolio) = GEmySQL->get ("select * from portfolio where portfolio.id=$hashref->{portfolio_id}");
}

Question: how do you read statement four? From left to right? or Right to left?

DBM::Deep::Iterator::File::BucketList(3pm)		User Contributed Perl Documentation		DBM::Deep::Iterator::File::BucketList(3pm)

NAME
DBM::Deep::Iterator::BucketList - mediate between DBM::Deep::Iterator and DBM::Deep::Engine::Sector::BucketList PURPOSE
This is an internal-use-only object for DBM::Deep. It acts as the mediator between the DBM::Deep::Iterator object and a DBM::Deep::Engine::Sector::BucketList sector. OVERVIEW
This object, despite the implied class hiearchy, does NOT inherit from DBM::Deep::Iterator. Instead, it delegates to it, essentially acting as a facade over it. "get_next_key" in DBM::Deep::Iterator will instantiate one of these objects as needed to handle an BucketList sector. METHODS
new(\%params) The constructor takes a hashref of params and blesses it into the invoking class. The hashref is assumed to have the following elements: o iterator (of type DBM::Deep::Iterator o sector (of type DBM::Deep::Engine::Sector::BucketList at_end() This takes no arguments. This returns true/false indicating whether this sector has any more elements that can be iterated over. get_next_iterator() This takes no arguments. This returns the next key pointed to by this bucketlist. This value is suitable for returning by FIRSTKEY or NEXTKEY(). If the bucketlist is exhausted, it returns nothing. perl v5.14.2 2012-06-24 DBM::Deep::Iterator::File::BucketList(3pm)
