i'm quite new to perl & haven't really used objects in perl before. i'm just trying to traverse a simple binary tree. the following will find the leftmost node, and print it out, but then it doesn't seem to GO anywhere--ie it doesn't seem to print out the higher nodes which called it, and move along to the right. anyone know what's up? is it something peculiar to perl (or have i just done something wrong)?
sub display
{ my $self = shift;
$self->displaynames($self->{root});
}
sub displaynames
{ my $self = shift;
$head = shift;
print $head->{Val}, " ";
if (defined ($head->{LRef}))
{ $self->displaynames($head->{LRef});
}
print $head->{Val}, "\n";
if (defined ($head->{RRef}))
{ $self->displaynames($head->{RRef});
}
}
