I'm weird with dereferencing objects.

In my prog oobjtest I want to get a list of objects.

Steps: in perl testprog oobjtest 1) Call a class method my @lo_hashref_objects = oclass::getemall();. Print them.

Steps: in perl class oclass

1. call another class method to get filecontent
2. content-lines store after split in an array my @lol by reference
3. pass this array to function getemall by return @lol. List-data are reachable by $array_ref->[$i]
4. Create a new object my $self = oclass->new;. Put data in instance variables by Setter functions.
5. Objects work, see Getter function output.
6. Store objects in an array. Data of objects available via $self as well as via array addressing, see getemall
7. Pass it to testprog oobjtest
8. Getting data out of list my @lol fails. Lack of syntax knowledge, but I cannot solve it.

The class file

I am trying to identify if a column Blaze[Info] contains within the text a string from a list (and create a new Boolean column with that information).

The DataFrame looks like:
