NAME ^

Object::Botox - simple object constructor with accessor, prototyping and default-settings of inheritanced values.

VERSION ^

Version 1.15

SYNOPSIS ^

Object::Botox writed for easy object creation by default constructor and support managment properties, inherited by children of prototyping class.

  package Parent;
  use Botox; # yes, we now are got |new| constructor
  
  # default properties for ANY object of `Parent` class:
  # prop1_ro ISA 'write-protected' && prop2 ISA 'public'
  # and seting default value for each other
  
  # strictly named constant PROTOTYPE !
  use constant PROTOTYPE => { 'prop1_ro' => 1 , 'prop2' => 'abcde' };

DESCRIPTION ^

Object::Botox - simple constructor and properties prototyper whith checking of properties existans.

To create parent module:

        package Parent;

        use Botox;
        
    # strictly named constant PROTOTYPE !
        use constant PROTOTYPE => {
                'prop1_ro' => 1 ,
                'prop2' => 'abcde'
                };
        
        sub show_prop1{ # It`s poinlessly - indeed property IS A accessor itself
                my ( $self ) = @_;
                return $self->prop1;
        }
        
        sub set_prop1{ # It`s NEEDED for RO aka protected on write property
                my ( $self, $value ) = @_;
                $self->prop1($value);
        }
        
        sub parent_sub{ # It`s class method itself
                my $self = shift;
                return $self->prop1;
        }
        1; 

after that we are create instanse:

        package main;
        use Data::Dumper;
        
        # change default value for prop1
        my $foo = new Parent( { prop1 => 888888 } );
        
        print Dumper($foo);

outputs get to us:

        $VAR1 = bless( {
                        'Parent::prop1' => 888888,
                        'Parent::prop2' => 'abcde'
                         }, 'Parent' );

properties may have _rw[default] or _ro acess mode and inheritated.

        eval{ $foo->prop1(-23) };
        print $@."\n";

output somthing like this:

        Can`t change RO properties |prop1| to |-23| in object Parent from main at ./test_more.t line 84

to deal (write to) with this properties we are must create accessor .

Also all of properties are inheritanced.

        package Child;  
        use base 'Parent';

        use constant PROTOTYPE => {
          'prop1' => 48,
          'prop5' => 55,
          'prop8_ro' => 'tetete'
                            };
        1;

give to us something like this

        $VAR1 = bless( {
                 'Child::prop5' => 55,
                 'Child::prop2' => 'abcde',
                 'Child::prop1' => 48,
                 'Child::prop8' => 'tetete'
               }, 'Child' );

Chainings - all setter return $self in success, so its chained

        $baz->prop1(88)->prop2('loreum ipsum');
