NAME

Moose::Meta::Attribute::Native::Trait::Number - Helper trait for Num attributes

VERSION

version 2.1005

SYNOPSIS

  package Real;
  use Moose;

  has 'integer' => (
      traits  => ['Number'],
      is      => 'ro',
      isa     => 'Num',
      default => 5,
      handles => {
          set => 'set',
          add => 'add',
          sub => 'sub',
          mul => 'mul',
          div => 'div',
          mod => 'mod',
          abs => 'abs',
      },
  );

  my $real = Real->new();
  $real->add(5);    # same as $real->integer($real->integer + 5);
  $real->sub(2);    # same as $real->integer($real->integer - 2);

DESCRIPTION

This trait provides native delegation methods for numbers. All of the operations correspond to arithmetic operations like addition or multiplication.

DEFAULT TYPE

If you don't provide an isa value for your attribute, it will default to Num.

PROVIDED METHODS

All of these methods modify the attribute's value in place. All methods return the new value.

  • add($value)

    Adds the current value of the attribute to $value.

  • sub($value)

    Subtracts $value from the current value of the attribute.

  • mul($value)

    Multiplies the current value of the attribute by $value.

  • div($value)

    Divides the current value of the attribute by $value.

  • mod($value)

    Returns the current value of the attribute modulo $value.

  • abs

    Sets the current value of the attribute to its absolute value.
