Workflow::Context - Data blackboard for Workflows, Actions, Conditions and Validators
This documentation describes version 1.62 of this package
# 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 ) );
Holds information to pass between your application and a Workflow, including its Actions, Conditions and Validators.
Adds %params to the context at instantiation.

Merges the values from $other_context into this object. If there are duplicate keys in this object and $other_context, $other_context wins.
