=head1 NAME
POE::Component::Jabber::ProtocolFactory
=head1 SYNOPSIS
PCJ::ProtocolFactory is a protected helper class used to instantiate specific
Protocols based on exported constants
=head1 DESCRIPTION
PCJ internally uses PCJ::ProtocolFactory to turn the ConnectionType argument
into a Protocol object used to implement the various supported dialects. This
is why the accepted arguments are exported as constants upon use.
=head1 FUNCTIONS
By default no functions are exported beyond the accepted arguments. Only a
package function is available:
=over 4
=item get_guts [Protected]
get_guts takes a single argument and that is a defined constant exported by
this module. It returns a PCJ::Protocol object.
See PCJ::Protocol for details on its methods and implementing different
Protocols.
=back
=head1 CONSTANTS
Below are the constants that are exported. Their names are rather
self-explanatory:
=over 4
=item XMPP
=item LEGACY
=item JABBERD14_COMPONENT
=item JABBERD20_COMPONENT
=back
=head1 NOTES
All supported Protocol types are implemented herein. get_guts will confess if it
receives an invalid argument.
