Description
Simply loading this module makes your constructors "strict". If your constructor is called with an
attribute init argument that your class does not declare, then it calls "Moose->throw_error()". This is a
great way to catch small typos.
SubvertingStrictness
You may find yourself wanting to have your constructor accept a parameter which does not correspond to an
attribute.
In that case, you'll probably also be writing a "BUILD()" or "BUILDARGS()" method to deal with that
parameter. In a "BUILDARGS()" method, you can simply make sure that this parameter is not included in the
hash reference you return. Otherwise, in a "BUILD()" method, you can delete it from the hash reference of
parameters.
sub BUILD {
my $self = shift;
my $params = shift;
if ( delete $params->{do_something} ) {
...
}
}
Donations
If you'd like to thank me for the work I've done on this module, please consider making a "donation" to
me via PayPal. I spend a lot of free time creating free software, and would appreciate any support you'd
care to offer.
Please note that Iamnotsuggestingthatyoumustdothis in order for me to continue working on this
particular software. I will continue to do so, inasmuch as I have in the past, for as long as it
interests me.
Similarly, a donation made in this way will probably not make me work on this software much more, unless
I get so many donations that I can consider working on free software full time (let's all have a chuckle
at that together).
To donate, log into PayPal and send money to autarch@urth.org, or use the button at
