java.lang.Objectorg.apache.velocity.app.event.EventHandlerUtil
Calls on request all registered event handlers for a particular event. Each method accepts two event cartridges (typically one from the application and one from the context). All appropriate event handlers are executed in order until a stopping condition is met. See the docs for the individual methods to see what the stopping condition is for that method.
