Revision history for Perl extension AMF::Perl.
0.15 Sun Sep 19 13:01:35 EDT 2004
Converted examples (except for Petmarket) to ActionScript 2.0 under Flash MX 2004.
Patches from Kostas Chatzikokolakis about error checking of input data length.
WriteUTF() writes the string length as long for lengths > 65535.
Also, check for (defined $s) and not just ($s) in writeUTF.
0.14 Sun Jul 11 18:59:36 EDT 2004
Really fixed the number 16 issue (forgot to include the change in 0.13).
Added Richard Boulton's change to readDouble() and writeDouble() to take into account endian-ness.
Changed the behavior of amf_throw() to enable die() to work.
0.13 Sun Jun 20 15:52:57 EDT 2004
Started duplicating changes in this file.

This shows various data types passed through AMF to the perl backend and sent back.
The most interesting this is not so much what it does, but how it works. The Perl script utilizes the "service discovery" approach - you simply put Perl modules into a certain directory, and they are automatically registered as services.
<br><br>
This example also shows how to throw exceptions, handled by functionName_onStatus in the Flash client (as opposed to functionName_onResult, which is called normally). Simply include in your Perl code
<pre>
use AMF::Perl qw/amf_throw/;
</pre>
and then call <em>amf_throw()</em> with a string or an arbitrary object as a parameter.
<br><br>
If you call <em>die "Error message"</em>, it will be also caught in the same way and sent as an error to Flash.

=head1 NAME
DataEcho
==head1 DESCRIPTION
Service class used in conjusction with basic.pl
All AMF::Perl service classes must define the method table, where the user can supply optional description and return type.
If you want to return an error message, handled by functionName_onStatus in the Flash client (as opposed to functionName_onResult, which is normal), include
use AMF::Perl qw/amf_throw/;
and then call amf_throw() with a string or an arbitrary object as a parameter.

did not go through.
