ActionInterface This is the interface you should implement to add an action to a BulkActions object for your listing.


Button A simple bulk action implementer that you can use when you just need a single button that triggers a callback when selected. Example usage:
Exception An exception sub-class for isolating errors related to bulk actions.
Result Communicate the result of processing your action. You can include a message and also specify whether it was successful or failed (e.g. an input validation error of some kind).
