Dear wise monks,
I have tried and tried and have failed to construct
an Array of Array (AoA) and access an element in that
AoA.
Here is the new method of my object ...
sub new {
my ( $pkg, $cols, $rows, $firstRow ) = @_;
# where first Row is a ref to an array.
my @AoA = ();
# deref $firstRow and push the first array
# into the array or arrays
push ( @AoA, @$firstRow );
for( my $row=1; $row<$rows; $row++ ) {
push( @AoA, [0..$cols] ); # I bet this wrong
}
bless {
cols => $cols,
rows => $rows,
AoA => @AoA
}, $pkg;
}
... The above new method does not cause a "compile time" error
but I suspect that it might be why this method does not work.
sub printElement {
$obj = shift;
$row = shift;
$col = shift;
print "AoA[$row][$col] = $obj->{AoA}[$row][$col]; # line 42
}
... The error I keey running into is ...
Can't use string ("blah") as array ref while "strict refs" in use at My.pm line 42.
What am I doing wrong here?
Thanks!
