=head1 NAME

RoPkg::DBCollection - base class who can be used for collections of database objects

=head1 VERSION

0.1.3

=head1 DESCRIPTION

RoPkg::DBCollection is a class who can be used as a base class
for database collection of objects. Is used by I<RoPkg::Simba::Mirrors>
,I<RoPkg::Simba::Commands> and I<RoPkg::Simba::Excludes>. This class
should not be used directly in applications but derived.

=head1 SUBROUTINES/METHODS

=head2 new()

The class constructor. Accepts a hash with parameters. The parameters
who can be passed to new() are:

=over 3

=item dbo - database object (instance of RoPkg::DB)

=item dbo_method - database method (for use with RoPkg::DB)

=item table - the sql table name where the objects data can be found

=back

If you don't specify the B<dbo> and B<dbo_method> parameters,
a I<Param::Missing> exception is raised.

=head2 dbh()

returns the database handler (DBI object) used by the class.

=head2 _count($fields)

Returns the number of records who match the fields specified in
$fields. This method should be overriden by the child classes.
The $fields must me specified in SQL::Abstract format. Please
refer to the SQL::Abstract documentation for more details about
$fields format.

=head2 _get($class_name, $fields, $order_by)

Returns a array of initialized objects. The values are read
from the database. $class_name is the name of the class
who's gonna be instanciated. When creating the class instance
dbo and dbo_method parameters are passed to the new() method.
The records from the database must match the $fields parameter
and the order is given by $order_by. For more details of these
2 parameters please refer to SQL::Abstract documentation.
 Exceptions throwed:
 
=over 3

=item B<Param::Missing> - when $class_name has not been specified

=item B<Param::Wrong> - when $class_name is not a class name

=item B<DB::NoResults> - when the query returned 0 results

=back
