[Bioperl-l] cut_seq in Bio::Tools::RestrictionEnzyme

[Staffa, Nick (NIH/NIEHS) [C]]

Please help me to understand the working of 
cut_seq in 
http://doc.bioperl.org/bioperl-live/Bio/Tools/RestrictionEnzyme.html#POD7
explicitly to extract the information contained in the return variable ---
some sort of reference to something. 
Documentation says
Title     : cut_seq
 Usage     : $re->cut_seq(<sequence object>);
 Purpose   : Conceptually cut or "digest" a DNA sequence with the given enzyme.
 Example   : $string = $re->cut_seq(<sequence object>); 
 Returns   : List of strings containing the resulting fragments.
 Argument  : Reference to a Bio::PrimarySeq.pm-derived object.

Eventually I want the length of the fragments.


Thank you.
