Re: Passing a Hash to another Object in MethodMaker

Disclaimer: I have never used Class::MethodMaker and think the documentation needs some copy editing, particularly as the documents for hash functionality are all dead links.

In Class::Method::array, where the array functionality is discussed, the array invocation is done through array references not arrays (i.e. array => [qw/ x /]). This implies to me that your issue is that you are passing it a hash (which would be an very poorly scaling interface indeed) in place of a hash ref. What happened when you tried that (I note a corresponding line in your source is commented out)?

Update: Found Class::Method::hash through some linking. From *_set, it appears that you are invoking it improperly. Have you tried

my $object = UPS::TrackedPackage->new;
$object->_returned_xml_set( %{$processedXML} );
return $object;
[download]

Update 2: Fixed a bad link.

Hi Kenneth, It does seem right that I was calling it incorrectly. The above still doesn't give me what I am after ... If I change `use Class::MethodMaker [ new => "new", scalar => 'debug' , hash => '_returned_xml' , ];` [download] to `use Class::MethodMaker [ new => "new", scalar => 'debug' , scalar => '_returned_xml' , ];` [download] and then... `my $object = UPS::TrackedPackage->new; return $object->_returned_xml('foo'); #The set seems out of date` [download] and with: : `my $tp = $Package->requestTrack(); #print $Package->_returned_xml(); print $tp->_returned_xml(); print Dumper($Package->_returned_xml());` [download] I get: Can't locate object method "_returned_xml" via package "foo" (perhaps you forgot to load "foo"?) at ootrack.pl line 32. It seems there may be something I am just not getting:-) Perhaps I might have better luck with a different OO library?	[reply] [d/l] [select]

There are a number of very popular OO frameworks (Moose, Mouse, Class::Struct, ...). Fixing what you have here, though, should be straight forward - from Class::Method::hash: If a single argument is provided that is an arrayref or hashref, it is expanded and its contents used in place of the existing contents In other words, replace `'foo'` in your code with `$processedXML`, you'll pass the hash and all will be well. Unless, of course, the documentation is lying.	[reply] [d/l] [select]

Hi Kenneth, Thank you for your help, the final working code is: `my $object = UPS::TrackedPackage->new(); $object->_returned_xml($processedXML); return $object;` [download] and `use Class::MethodMaker [ new => "new", scalar => 'debug' , scalar => '_returned_xml' , ];` [download]	[reply] [d/l] [select]
