MooseX::AttributeHelpers::Number
package Real; use Moose; use MooseX::AttributeHelpers; has 'integer' => ( metaclass => 'Number', is => 'ro', isa => 'Int', default => sub { 5 }, provides => { 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);
This provides a simple numeric attribute, which supports most of the basic math operations.
It is important to note that all those methods do in place modification of the value stored in the attribute.
Alternate way to set the value.
Adds the current value of the attribute to $value.
$value
Subtracts the current value of the attribute to $value.
Multiplies the current value of the attribute to $value.
Divides the current value of the attribute to $value.
Modulus the current value of the attribute to $value.
Sets the current value of the attribute to its absolute value.
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
