jeffa has asked for the
wisdom of the Perl Monks concerning the following question:
I am playing with objects and came across a stumbling block.
I have a Person class that appears to be correctly coded, but I will print it at the bottom of my question just in case. My problem is in the use of said class.
The Person class has a data field called NAME and method to set and get it's value called name(). My client code instantiates a number of Person objects and stores them in a list:
No problems here, now let's say that I want to iterate through list and print the names of my employees:
Uh oh - upon trying to interpret the script, Perl yacks:
Can't call method "name" on unblessed reference at ./foo.pl line xx
So I changed the print statement to:
ARRAY Person Person Person Person Person Person Person
Can anyone tell me where did that ARRAY came from?
Here is my Person class as promised: (can anyone say Perltoot?)
