NAME
Moose::Meta::Attribute::Native::Trait::Number - Helper trait for Num attributes
VERSION
version 2.2203
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.
