POE::Session::Cascading 1.03

POE::Session::Cascading is a Perl module with stack-like POE sessions.

SYNOPSIS

POE::Session::Cascading->new(
name => foo,
events => [
state1 => &state1,
state2 => &state2,
],
);

sub state1 {
my %args = @_;
$args{KERNEL}->post(somewhere,somestate);
# [ snip ]

}

sub state2 {
my %args = @_;
# [ snip ]

$args{SESSION}->stop;
}

POE::Session::Cascading provides a stack-like session for POE. Another way of saying it is that a Cascading session is like a big switch statement. In the above example, when state1 is called in session foo, &state1 gets executed. When it finishes, state2 gets fired and &state2 gets executed. If state2 is called in session foo, only state2 will get executed.
