MouseX::NativeTraits::UsertContributed Perl DoMouseX::NativeTraits::Counter(3)

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.
