=head1 NAME
Sub::HandlesVia::HandlerLibrary::Scalar - library of scalar-related methods
=head1 SYNOPSIS
package My::Class {
use Moo;
use Sub::HandlesVia;
use Types::Standard 'Any';
has attr => (
is => 'rwp',
isa => Any,
handles_via => 'Scalar',
handles => {
'my_get' => 'get',
'my_make_getter' => 'make_getter',
'my_make_setter' => 'make_setter',
'my_scalar_reference' => 'scalar_reference',
'my_set' => 'set',
'my_stringify' => 'stringify',
},
);
}
=head1 DESCRIPTION
This is a library of methods for L<Sub::HandlesVia>.
=head1 DELEGATABLE METHODS
=head2 C<< get() >>
Gets the current value of the scalar.
=head2 C<< make_getter() >>
Returns a getter coderef.
my $object = My::Class->new( attr => 10 );
my $getter = $object->my_make_getter;
$object->_set_attr( 11 );
say $getter->(); ## ==> 11
=head2 C<< make_setter() >>
Returns a setter coderef.
my $object = My::Class->new( attr => 10 );
my $setter = $object->my_make_setter;
$setter->( 11 );
say $object->attr; ## ==> 11
=head2 C<< scalar_reference() >>
Returns a scalar reference to the attribute value's slot within its object.
my $object = My::Class->new( attr => 10 );
my $ref = $object->my_scalar_reference;
$$ref++;
say $object->attr; ## ==> 11
=head2 C<< set( $value ) >>
Sets the scalar to a new value.
=head2 C<< stringify() >>
Gets the current value of the scalar, but as a string.
