Monks,
Is it possible to retrieve the attribute name that is currently being set in a builder method - similar to what
caller() does?
Maybe an example will better explain what is required:
package This::That;
use Moose;
has 'FOO' => (is => 'rw', lazy => 1, builder=> '_build_generic');
has 'BAR' => (is => 'rw', lazy => 1, builder=> '_build_generic');
with qw(SQLConnection);
sub _build_generic {
my $self = shift;
#my $attribute_name = $self->meta->???? - is it possible to determi
+ne 'FOO' or 'BAR' is being set here ???
#my $sth = $self->dbh->prepare('select $attribute_name from table wh
+ere x=? and y=?');
#$sth->execute(1,2);
return $sth->fetchrow_array;
}
The obvious alternative is to write separate builder methods for each attribute. However, this can lead to unnecessary repetition, where the only item that is changing is the attribute name.
