NAME

XAO::DO::Web::Action - base for mode-dependant displayable objects

SYNOPSIS

 package XAO::DO::Web::Fubar;
 use strict;
 use XAO::Objects;
 use XAO::Errors qw(XAO::DO::Web::Fubar);
 use base XAO::Objects->load(objname => 'Web::Action');

 sub check_mode ($$) {
     my $self=shift;
     my $args=get_args(\@_);
     my $mode=$args->{mode};
     if($mode eq "foo") {
         $self->foo($args);
     }
     elsif($mode eq "kick") {
         $self->kick($args);
     }
     else {
         $self->SUPER::check_mode($args);
     }
 }

DESCRIPTION

Very simple object with overridable check_mode method. Simplifies implementation of objects with arguments like:

 <%Fubar mode="kick" target="ass"%>

Default check_mode() method does not have any functionality and always simply throws an error with the content of 'mode':

 throw $self "check_mode - unknown mode ($mode)";

Remember that using "throw $self" you actually throw an error that depends on the namespace of your object and therefor can be caught separately if required.

EXPORTS

Nothing.
