I’ve recently inherited some code that hasn’t been touched in over 5 years.
It’s all cgi and OOPerl.
I’ve ran across this one statement that I don’t understand.
$self->log->error(*)
I know the self
and I’ve traced the error to CGI::Application through inheritance.
But it’s the ->log-> that has me confused.
I have no class named log
I find no place that is does a new on log anywhere in the family tree.
I cannot find any log class anywhere in the family tree of inheritance.
Is this just a method of using a perl hash that I’m not familiar with?
Could it be rewritten as
$self->{‘log’}->error(*);
