Moose::Cookbook::Basics::Person_BUILDARGSAndBUILD - Using BUILDARGS and BUILD to hook into object construction
VERSION
version 2.0604
SYNOPSIS
package Person;
has 'ssn' => (
is => 'ro',
isa => 'Str',
predicate => 'has_ssn',
);
has 'country_of_residence' => (
is => 'ro',
isa => 'Str',
default => 'usa'
);
has 'first_name' => (
is => 'ro',
isa => 'Str',
);
has 'last_name' => (
is => 'ro',
isa => 'Str',
);
around BUILDARGS => sub {
my $orig = shift;
my $class = shift;
if ( @_ == 1 && ! ref $_[0] ) {
return $class->$orig(ssn => $_[0]);
}
else {
return $class->$orig(@_);
}
};
sub BUILD {
my $self = shift;
if ( $self->country_of_residence eq 'usa' ) {
die 'Cannot create a Person who lives in the USA without an ssn.'
unless $self->has_ssn;
}
}
DESCRIPTION
This recipe demonstrates the use of "BUILDARGS" and "BUILD". By defining these methods, we can hook into the object construction process
without overriding "new".
The "BUILDARGS" method is called before an object has been created. It is called as a class method, and receives all of the parameters
passed to the "new" method. It is expected to do something with these arguments and return a hash reference. The keys of the hash must be
attribute "init_arg"s.
The primary purpose of "BUILDARGS" is to allow a class to accept something other than named arguments. In the case of our "Person" class,
we are allowing it to be called with a single argument, a social security number:
my $person = Person->new('123-45-6789');
The key part of our "BUILDARGS" is this conditional:
if ( @_ == 1 && ! ref $_[0] ) {
return $class->$orig(ssn => $_[0]);
}
By default, Moose constructors accept a list of key-value pairs, or a hash reference. We need to make sure that $_[0] is not a reference
before assuming it is a social security number.
We call the original "BUILDARGS" method to handle all the other cases. You should always do this in your own "BUILDARGS" methods, since
Moose::Object provides its own "BUILDARGS" method that handles hash references and a list of key-value pairs.
The "BUILD" method is called after the object is constructed, but before it is returned to the caller. The "BUILD" method provides an
opportunity to check the object state as a whole. This is a good place to put logic that cannot be expressed as a type constraint on a
single attribute.
In the "Person" class, we need to check the relationship between two attributes, "ssn" and "country_of_residence". We throw an exception if
the object is not logically consistent.
MORE CONSIDERATIONS
This recipe is made significantly simpler because all of the attributes are read-only. If the "country_of_residence" attribute were
settable, we would need to check that a Person had an "ssn" if the new country was "usa". This could be done with a "before" modifier.
CONCLUSION
We have repeatedly discouraged overriding "new" in Moose classes. This recipe shows how you can use "BUILDARGS" and "BUILD" to hook into
object construction without overriding "new".
The "BUILDARGS" method lets us expand on Moose's built-in parameter handling for constructors. The "BUILD" method lets us implement logical
constraints across the whole object after it is created.
