NAME

       accessors::classic - create 'classic' read/write accessor methods in caller's package.

SYNOPSIS

         package Foo;
         use accessors::classic qw( foo bar baz );

         my $obj = bless {}, 'Foo';

         # always return the current value, even on set:
         $obj->foo( 'hello ' ) if $obj->bar( 'world' ) eq 'world';

         print $obj->foo, $obj->bar, $obj->baz( "!\n" );

DESCRIPTION

       The accessors::classic pragma lets you create simple classic Perl accessors at compile-
       time.

       The generated methods look like this:

         sub foo {
             my $self = shift;
             $self->{foo} = shift if (@_);
             return $self->{foo};
         }

       They always return the current value.

       Note that there is no dash ("-") prepended to the property name as there are in accessors.
       This is for backwards compatibility.

PERFORMANCE

       There is little-to-no performace hit when using generated accessors; in fact there is
       usually a performance gain.

       •   typically 5-15% faster than hard-coded accessors (like the above example).

       •   typically 1-15% slower than optimized accessors (less readable).

       •   typically a small performance hit at startup (accessors are created at compile-time).

       •   uses the same anonymous sub to reduce memory consumption (sometimes by 80%).

       See the benchmark tests included with this distribution for more details.

CAVEATS

       Classes using blessed scalarrefs, arrayrefs, etc. are not supported for sake of
       simplicity.  Only hashrefs are supported.
