NAME

    Class::Tiny::Immutable - Minimalist class construction, with read-only
    attributes

SYNOPSIS

    In Person.pm:

      package Person;
      
      use Class::Tiny::Immutable qw( name );
      
      1;

    In Employee.pm:

      package Employee;
      use parent 'Person';
      
      use Class::Tiny::Immutable qw( ssn ), {
        timestamp => sub { time }   # lazy attribute with default
      };
      
      1;

    In example.pl:

      use Employee;
      
      my $obj = Employee->new; # dies, name and ssn attributes are required
      my $obj = Employee->new( name => "Larry", ssn => "111-22-3333" );
      
      my $name = $obj->name;
      my $timestamp = $obj->timestamp;
      
      # no attributes can be set
      $obj->ssn("222-33-4444"); # dies
      $obj->timestamp(time); # dies

DESCRIPTION

    Class::Tiny::Immutable is a wrapper around Class::Tiny which makes the
    generated attributes read-only, and required to be set in the object
    constructor if they do not have a lazy default defined. In other words,
    attributes are either "lazy" or "required".

METHODS

    In addition to methods inherited from Class::Tiny,
    Class::Tiny::Immutable defines the following additional introspection
    method:

 get_all_required_attributes_for

      my @required = Class::Tiny::Immutable->get_all_required_attributes_for($class);

    Returns an unsorted list of required attributes known to
    Class::Tiny::Immutable for a class and its superclasses.
