SYNOPSIS

13        # Create your own context and merge it with one that may already be
14        # in a workflow
15
16        my $context = Workflow::Context->new();
17        $context->param( foo => 'bar' );
18        $context->param( current_user => User->fetch( 'foo@bar.com' ) );
19        my $wf = FACTORY()->create_workflow( 'w/f', $context );
20
21        # The above is the same as:
22        $context = Workflow::Context->new(
23             foo   => 'bar',
24             current_user => User->fetch( 'foo@bar.com' ),
25        );
26        $wf = FACTORY()->create_workflow( 'w/f', $context );
27
28
29        # In a Condition get the 'current_user' back out of the workflow's context
30
31        sub evaluate {
32            my ( $self, $wf ) = @_;
33            my $current_user = $wf->context->param( 'current_user' );
34            ...
35        }
36
37        # Set values directly into a workflow's context
38
39        $wf->context->param( foo => 'bar' );
40        $wf->context->param( news => My::News->fetch_where( 'date = ?', DateTime->now ) );
