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.
