MouseX::NativeTraits::Counter(3pm) User Contributed Perl Documentation MouseX::NativeTraits::Counter(3pm)NAMEMouseX::NativeTraits::Counter - Helper trait for counter attributesSYNOPSISpackage 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 );DESCRIPTIONThis 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']); $obj->inc_foo;PROVIDED METHODSThese methods are implemented in MouseX::NativeTraits::MethodProvider::Counter. It is important to note that all those methods do in place modification of the value stored in the attribute. set($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.METHODSmeta method_provider_class helper_typeSEE ALSOMouseX::NativeTraits perl v5.14.2 2011-12-04 MouseX::NativeTraits::Counter(3pm)
