NAME

Workflow::Context - Data blackboard for Workflows, Actions, Conditions and Validators

VERSION

This documentation describes version 1.62 of this package

SYNOPSIS

# Create your own context and merge it with one that may already be
# in a workflow

my $context = Workflow::Context->new();
$context->param( foo => 'bar' );
$context->param( current_user => User->fetch( 'foo@bar.com' ) );
my $wf = FACTORY()->create_workflow( 'w/f', $context );

# The above is the same as:
$context = Workflow::Context->new(
     foo   => 'bar',
     current_user => User->fetch( 'foo@bar.com' ),
);
$wf = FACTORY()->create_workflow( 'w/f', $context );


# In a Condition get the 'current_user' back out of the workflow's context

sub evaluate {
    my ( $self, $wf ) = @_;
    my $current_user = $wf->context->param( 'current_user' );
    ...
}

# Set values directly into a workflow's context

$wf->context->param( foo => 'bar' );
$wf->context->param( news => My::News->fetch_where( 'date = ?', DateTime->now ) );
