MooseX::Attribute::ChainedClone - Attribute that returns a cloned instance
version 1.0.3
package Test; use Moose; has debug => ( traits => [ 'ChainedClone' ], is => 'rw', isa => 'Bool', default => 0, ); sub complex_method { my $self = shift; #... print "helper message" if $self->debug; #... } sub clone { my $self = shift; # custom clone code here # defaults to: return bless { %$self }, ref $self; } 1;
Which allows for:
my $test = Test->new; $test->debug(1)->complex_method; # debug enabled # complex_method is called on a cloned instance # with debug set to 1 $test->complex_method; # debug is still disabled on $test $test->debug(1); # returns a cloned $test instance with debug set to 1 $test->debug; # returns 0
MooseX::Attribute::ChainedClone is a Moose Trait which allows for method chaining on accessors by returning a cloned instance of $self on write/set operations.
$self
If $self has a clone method, this method is invoked to clone the instance. This allows for easy integration with MooseX::Clone or any custom made clone method. If no clone method is available, the new instance is build using bless { %$self }, ref $self.
clone
bless { %$self }, ref $self
