NAME

Class::Workflow::State::AutoApply - Automatically apply a transition upon arriving into a state.

SYNOPSIS

package MyState;
use Moose;

with qw/Class::Workflow::State::AutoApply/;

my $state = Mystate->new( auto_transition => $t );

my $i2 = $state->accept_instance( $i, @args ); # automatically calls $t->apply( $i, @args )

DESCRIPTION

This state role is used to automatically apply a transition

PARTIAL TRANSITIONS

If an auto-application may fail validation or something of the sort you can do something like:

around apply_auto_transition => sub {
	my $next = shift;
	my ( $self, $instance, @args ) = @_;

	eval { $self->$next( $instance, @args ) }

	die $@ unless $@->isa("SoftError");
}

If apply_auto_transition returns a false value then the original instance will be returned automatically, at which point the intermediate state is the current state.
