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.
