NAME

MouseX::NativeTraits::Counter - Helper trait for counter attributes

SYNOPSIS

  package MyHomePage;
  use Mouse;

  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 );

DESCRIPTION

This module provides a simple counter attribute, which can be incremented and decremented.

If your attribute definition does not include any of is, isa, default or handles but does use the "Counter" trait, then this module applies defaults as in the "SYNOPSIS" above. This allows for a very basic counter definition:

  has 'foo' => (traits => ['Counter']);
  $obj->inc_foo;

PROVIDED METHODS

These methods are implemented in MouseX::NativeTraits::MethodProvider::Counter. It is important to note that all those methods do in place modification of the value stored in the attribute.

set($value): Set the counter to the specified value.
inc: Increments the value stored in this slot by 1. Providing an argument will cause the counter to be increased by specified amount.
dec: Decrements the value stored in this slot by 1. Providing an argument will cause the counter to be increased by specified amount.
reset: Resets the value stored in this slot to it's default value.
