=head1 SYNOPSIS
|
|

|
package Real;
|
|
use Moose;
|
|
|
|
has 'integer' => (
|
|
traits => ['Number'],
|
|
is => 'ro',
|
|
isa => 'Num',
|
|
default => 5,
|
|
handles => {

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

$real->sub(2); # same as $real->integer($real->integer - 2);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This trait provides native delegation methods for numbers. All of the
|
|
operations correspond to arithmetic operations like addition or
|
|
multiplication.
|
|
|
|
=head1 DEFAULT TYPE
|
|
|
|
If you don't provide an C<isa> value for your attribute, it will default to
|
|
C<Num>.
|
|
|
|
=head1 PROVIDED METHODS
|
|
|
|
All of these methods modify the attribute's value in place. All methods return
|
|
the new value.
|
|
|
|
=over 4
|
|
|
|
=item * B<add($value)>
|
|
|
|
Adds the current value of the attribute to C<$value>.
|
|
|
|
=item * B<sub($value)>
|
|
|
|
Subtracts C<$value> from the current value of the attribute.
|
|
|
|
=item * B<mul($value)>
|
|
|
|
Multiplies the current value of the attribute by C<$value>.
|
|
|
|
=item * B<div($value)>
|
|
|
|
Divides the current value of the attribute by C<$value>.
|
|
|
|
=item * B<mod($value)>
|
|
|
|
Returns the current value of the attribute modulo C<$value>.
|
|
|
|
=item * B<abs>
|
|
|
|
Sets the current value of the attribute to its absolute value.
