Re: filehandler stored in hash-ref

thnx alot! also for explaining that its a handle not a handler :)

One last (almost related) thing. I'm using Tie::Hash, so if the programs dies (because it cannot open the file), the DESTROY sub is called:

sub DESTROY {
  my $self = shift ;
  if ( $self->{out} && $self->{out}->opened() ) {
    ... do stuff ....
    close $self->{out} ;
  }
}
[download]

$self->{out} is the filehandle mentioned in my first post. Unfortunatly this generates the following

(in cleanup) Can't locate object method "opened" via package "IO::Hand
+le" at modules/MyTH.pm line 29.
[download]

So the question is how do I test if a filehandle is open ?

Perhaps you forgot to load IO::Handle...	[reply]

thats it! But, if I see this `(in cleanup) Can't locate object method "opened" via package "IO::Hand +le"` [download] I would say IO::Handle is already loaded, because its already using this package !	[reply] [d/l]

All handles are virtually blessed to IO::Handle `$ perl -e'STDOUT->autoflush(1)' Can't locate object method "autoflush" via package "IO::Handle" at -e +line 1.` [download] That doesn't mean the module is loaded: `$ perl -e'(bless {}, "Foo::Bar")->doit()' Can't locate object method "doit" via package "Foo::Bar" at -e line 1.` [download]	[reply] [d/l] [select]

You can bless some reference into a class without the class (package) being loaded. `my $demo = bless {}, 'I::Just::Made::This::Up'; print "Things in UNIVERSAL:: work.\n" if $demo->isa('I::Just::Made::Th +is::Up'); $demo->opened(); __END__ Things in UNIVERSAL:: work. Can't locate object method "opened" via package "I::Just::Made::This:: +Up"` [download]	[reply] [d/l]
