NAME

    Data::Object::Role::Formulatable - Objectify Class Attributes

ABSTRACT

    Formulatable Role for Perl 5

SYNOPSIS

      package Test::Student;
    
      use registry;
      use routines;
    
      use Data::Object::Class;
      use Data::Object::ClassHas;
    
      with 'Data::Object::Role::Formulatable';
    
      has 'name';
      has 'dates';
    
      sub formulate {
        {
          name => 'test/data/str',
          dates => 'test/data/str'
        }
      }
    
      package main;
    
      my $student = Test::Student->new({
        name => 'levi nolan',
        dates => ['1587717124', '1587717169']
      });
    
      # $student->name;
      # <Test::Data::Str>
    
      # $student->dates;
      # [<Test::Data::Str>]

DESCRIPTION

    This package provides a mechanism for automatically inflating objects
    from constructor arguments.

INTEGRATES

    This package integrates behaviors from:

    Data::Object::Role::Buildable

LIBRARIES

    This package uses type constraints from:

    Types::Standard

SCENARIOS

    This package supports the following scenarios:

 automation

      package Test::Teacher;
    
      use registry;
      use routines;
    
      use Data::Object::Class;
      use Data::Object::ClassHas;
    
      with 'Data::Object::Role::Formulatable';
    
      has 'name';
      has 'dates';
    
      sub formulate {
        {
          name => 'test/data/str',
          dates => 'test/data/str'
        }
      }
    
      sub after_formulate {
        {
          name => 1
        }
      }
    
      sub after_formulate_name {
        my ($self, $value) = @_;
    
        $value
      }
    
      sub before_formulate {
        {
          name => 1
        }
      }
    
      sub before_formulate_name {
        my ($self, $value) = @_;
    
        $value
      }
    
      package main;
    
      my $teacher = Test::Teacher->new({
        name => 'levi nolan',
        dates => ['1587717124', '1587717169']
      });
    
      # $teacher->name;
      # <Test::Data::Str>
    
      # $teacher->dates;
      # [<Test::Data::Str>]

    This package supports automatically calling "before" and "after"
    routines specific to each piece of data provided. This is automatically
    enabled if the presence of a before_formulate and/or after_formulate
    routine is detected. If so, these routines should return a hashref
    keyed off the class attributes where the values are either 1 (denoting
    that the hook name should be generated) or some other routine name.
