Mo::builder - Adds the builder feature to Mo's has
use Mo qw'builder'; has name => ( builder => 'name_lookup' );
sub name_lookup { my ($self) = @_; ... }
Adds the builder
parameter to has, which expects a method name, which is
executed on $self
to set the attribute if it hasn't been set yet.
Builders in Mo are lazy by default.
This can be changed by explicitly setting the lazy
argument to false, in
order to cause it to be initialized during instantiation.
use Mo qw'builder'; has status => ( builder => '_build_status' ); # lazy has source => ( builder => '_build_source', lazy => 1); # lazy has target => ( builder => '_build_target', lazy => 0); # eager
To change the default behavior and make builders to be initialized eagerly
by default, import nonlazy
.
use Mo qw'builder nonlazy'; has status => ( builder => '_build_status' ); # eager has source => ( builder => '_build_source', lazy => 1); # lazy has target => ( builder => '_build_target', lazy => 0); # eager
