( [id://3333] : superdoc . print w/replies, xml ) Need Help??

The magic of tie seems to be strong. Even when using a reference to an element of a tied array one cannot bypass the associated class. And the access through the reference provides the correct index. So is this what happens when Perl aliases elements in a loop?

use strict; use warnings; package MyClass; use Tie::Array; our @ISA = ('Tie::Array'); our @data; # mandatory methods sub TIEARRAY { my $class = shift; bless \@data, $class; @data = @_ +; return \@data } sub FETCH { my ($self, $index ) = @_; print "FETCH($index)\n"; ret +urn $data[$index] } sub STORE { my ($self, $index, $value) = @_; print "STORE($index)\ +n"; $data[$index] = $value } sub FETCHSIZE { print "<FETCHSIZE> "; return scalar @data } package main; my @x; tie @x, "MyClass", 0, 0, 0; my $x = \$x[2]; $$x++; print "@x\n";

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
