I have a class definition:
class Etran {
has $.dstamp is rw;
has $.folio is rw;
has $.ticker is rw;
has $.qty is rw;
has $.amount is rw;
has $.desc is rw;
method new($line) {
my ($cmd, $dstamp, $folio, $ticker, $qty, $amount, $way, $desc)
= shlex-fields $line;
$!dstamp = $dstamp;
$!folio = $folio;
$!ticker = $ticker;
$!qty = $way == "B" ?? $qty !! - $qty;
$!amount = $amount;
$!desc = $desc;
}
}**
which I instantiate with
my $e = Etran.new($line);
However, it gives an error message:
Cannot look up attributes in a Etran type object
at the line
$!dstamp = $dstamp;
Why that, and how do I fix it?
Also, I don't really understand the difference between using the twigils "." and using
"!",
and have yet to see an explanation that I understand.
