[Bioperl-l] Detecting type of an object.

[hilmar.lapp@pharma.Novartis.com]

I'm not sure why you want to test the object type in this case. Anyway, you
can ask

   $class_name = ref($obj);
   # branch depending on the value of class_name

and

   if(! $obj->isa('Bio::PrimarySeqI')) {
      print "Object $obj is not a BioPerl seq object\n";
   }

Does this help?

Subject:  [Bioperl-l] Detecting type of an object.


I am wondering if it is possible to detect the type of an object.
For instance, I have written a module that parses a blast report to select
a
sequence. The module returns the sequence as a Bio::Seq object if the
parsing
was succesful and some error message when there was no good hit found.
Now when I use this module in a script I would like to test whether or not
there is a sequence found before doing something with the sequence. Is
there a
proper way to tackle such a problem?

Thanks,
Gert Thijs
