Module OpenWFE::WorkItemListener
In: lib/openwfe/listeners/listener.rb

this mixin module provides two protected methods, handle_item() and filter_item(). They can be easily overriden to add some special behaviours.

Methods

filter_items   handle_item  

Included Modules

Contextual Logging OwfeServiceLocator

Protected Instance methods

filter_items(item)

The base implementation is just empty, feel free to override it if you need to filter workitems.

One example : 

    class MyListener
        include WorkItemListener

        protected

            #
            # MyListener doesn't accept launchitems
            #
            def filter_items (item)
                raise "launchitems not allowed"              #                     if item.is_a?(OpenWFE::LaunchItem)
            end
    end

91:                 #    "listener of class '#{self.class.name}' "+
92:                 #    "doesn't accept launchitems")
93:             end
handle_item(item)

Simply considers the object as a workitem and feeds it to the engine.
