Re^2: Generating accessors for complex structures inside the object

[KSURi]

I've read your code attentively, now I want to ask a few questions please. Here:

...
   D => {
      E => {
         F => 'G'
      }
   },
##   Z => 'G', # Duplicate test
...

If I'll uncomment 'Z' key there will be a warning thrown about duplicate 'G' key. But 'G' is not a key here, it's keys value.

And here:

##   X => [1,2,3], # Bad type test

Why arrayref is a bad type?

And the last one: I tried to add mutators to your code through assignment the lvalue attribute to _derefernce sub but it has no effect =( Any ideas of how can I do this?

Hi KSURi,

Thanks for your questions. Before getting into the details; I did make some assumptions that need to be tested:

The class level structure (defined in Foo) is a effectively a struct definition:

So, if in Foo, you define

package Foo;
use base qw/Class::StructAccessors/;
__PACKAGE__->mk_struct_accessors({A => {B => C}});

then the actual method created is C.

my $obj = {};
bless $obj, "Foo";
$obj->{A}{B}{C} = "this is a C";
print $obj->C; # outputs  "this is a C"

If you want another object with another fixed structure, then you need another class

package Bar;
use base qw/Class::StructAccessors/;
__PACKAGE__->mk_struct_accessors({X => {Y => Z}});

This will generate accessor method for Z.

In an nutshell, the above code works when you have finite number of structures that are know at run time.

I'm getting the feeling that you want a more dynamic solution that'll work at the instance on any structure; something like:

my $obj = bless {a => {b => {c  => 'data  for c'}}},  "Class::StructAc
+cessorMk2";

Always happy to assist (and code) :-) Please advise.

> I'm getting the feeling that you want a more dynamic solution that'll work at the instance on any structure; Yep, that will be very usefull not only for me. Though I've solved my own problem (through object redesigning) I'll be glad to read ideas and etc. Thanks for your assist)
