NAME

Class::Init - A base constructor class with support for local initialization methods.

SYNOPSIS

package Something::Spiffy;
use base qw(Class::Init);

sub _init {
  my $self = shift;
  exists $self->{dsn} || die "parameter 'dsn' missing";
  $self->{_dbh} = DBI->connect($self->{dsn}) || die "DBI->connect failed";
}

package main;

my $database = Something::Spiffy->new( dsn => '...' );
my @users = $database->{_dbh}->...;

DESCRIPTION

Class::Init provides a constructor, new(), that returns blessed hashrefs by default; that constructor runs all instances of the subroutine _init it finds in the inheritance tree, top-down (EVERY).

The goal of this module is to reduce the amount of effort required to construct a simple object class; it helps reduce the amount of code that's duplicated between classes by providing a generic constructor, while allowing individual classes a low-effort way to publish their own changes to the new object.
