Laudetur, monks.
I began to learn objects in Perl. In my testscript I create a filehandler object. Note: I know that there are proven and comfortable ways to do it, but this is about practicing.
Code:
#!/usr/bin/perl
use strict;
use warnings;
{package MyFilehandler;
my $fh;
sub openForRead {
my $class = shift;
my $filename = shift;
bless \$filename, $class;
open (FH, '<', $filename) or die "could not open file: $!";
$fh = \*FH;
}
sub writeout {
my @lines = <$fh>;
print @lines;
}
}
my $testfh = MyFilehandler->openForRead("betvek");
$testfh->writeout;
Error message:
#Can't locate object method "writeout" via package "IO::File" at fileobj.pl line 25 (line 25 is
$testfh->writeout;
Writeout is right there, same package. This must be a very basic error but I'm stuck for hours. Your help is appreciated.
