package org.apache.tapestry5.corelib.components;
A close relative of ActionLink except in two ways.

First, the event that it triggers is explicitly controlled, rather than always "action".

Second, the event is triggered in its container.

This allows slightly shorter URLs but also allows multiple components within the same container to generate identical URLs for common actions.

public class EventLink extends AbstractComponentEventLink
{
    
The name of the event to be triggered in the parent component. Defaults to the id of the component. An ActionLink triggers an "action" event on itself, and EventLink component triggers any arbitrary event on its container.
    @Parameter(defaultPrefix = .)
    private String event;
    @Inject
    private ComponentResources resources;
    {
        return .getId();
    }
    @Override
    protected Link createLink(Object[] eventContext)
    {
        ComponentResources containerResources = .getContainerResources();
        return containerResources.createEventLink(eventContext);
    }
