NAME 🖥️ Moose_Meta_Attribute_Native_Trait_Counterpm 🖥️

Helper trait for Int attributes which represent counters

VERSION

version 2.2207

SYNOPSIS

package MyHomePage; use Moose; has counter => ( traits => [Counter], is => ro, isa => Num, default => 0, handles => { inc_counter => inc, dec_counter => dec, reset_counter => reset, }, ); my $page = MyHomePage->new(); $page->inc_counter; # same as $page->counter( $page->counter + 1 ); $page->dec_counter; # same as $page->counter( $page->counter - 1 ); my $count_by_twos = 2; $page->inc_counter($count_by_twos);

DESCRIPTION

This trait provides native delegation methods for counters. A counter can be any sort of number (integer or not). The delegation methods allow you to increment, decrement, or reset the value.

DEFAULT TYPE

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

PROVIDED METHODS

  • set($value) Sets the counter to the specified value and returns the new value. This method requires a single argument.

  • inc

  • inc($arg) Increases the attribute value by the amount of the argument, or by 1 if no argument is given. This method returns the new value. This method accepts a single argument.

  • dec

  • dec($arg) Decreases the attribute value by the amount of the argument, or by 1 if no argument is given. This method returns the new value. This method accepts a single argument.

  • reset Resets the value stored in this slot to its default value, and returns the new value.
