class::dbi::search::basic
Class::DBI::Search::Basic(3pm) User Contributed Perl Documentation Class::DBI::Search::Basic(3pm)
NAME
Class::DBI::Search::Basic - Simple Class::DBI search
SYNOPSIS
my $searcher = Class::DBI::Search::Basic->new(
$cdbi_class, @search_args
);
my @results = $searcher->run_search;
# Over in your Class::DBI subclass:
__PACKAGE__->add_searcher(
search => "Class::DBI::Search::Basic",
isearch => "Class::DBI::Search::Plugin::CaseInsensitive",
);
DESCRIPTION
This is the start of a pluggable Search infrastructure for Class::DBI.
At the minute Class::DBI::Search::Basic doubles up as both the default search within Class::DBI as well as the search base class. We will
probably need to tease this apart more later and create an abstract base class for search plugins.
METHODS
new
my $searcher = Class::DBI::Search::Basic->new(
$cdbi_class, @search_args
);
A Searcher is created with the class to which the results will belong, and the arguments passed to the search call by the user.
opt
if (my $order = $self->opt('order_by')) { ... }
The arguments passed to search may contain an options hash. This will return the value of a given option.
run_search
my @results = $searcher->run_search;
my $iterator = $searcher->run_search;
Actually run the search.
SUBCLASSING
sql / bind / fragment
The actual mechanics of generating the SQL and executing it split up into a variety of methods for you to override.
run_search() is implemented as:
return $cdbi->sth_to_objects($self->sql, $self->bind);
Where sql() is
$cdbi->sql_Retrieve($self->fragment);
There are also a variety of private methods underneath this that could be overridden in a pinch, but if you need to do this I'd rather you
let me know so that I can make them public, or at least so that I don't remove them from under your feet.
