In Moose, how to specify constructor arguments for the superclass in a subclass?

I have a Moose class with some properties (x,y,z). I subclass it, and for the subclass, x is always 3. How can I specify this in subclass?

Solution

  • One could use BUILDARGS.

    around BUILDARGS => sub {
    my $orig  = shift;
    my $class = shift;
 
    return $class->$orig(@_, x => 3 );
};
