Interface Action

All Superinterfaces:

Serializable

All Known Implementing Classes:

AbstractAction, ClickAction, ClipboardCopyAction, JsAction, ServerCallbackAction, SetEnabledAction

public interface Action
extends Serializable

Something that runs on the client when a Trigger fires.

An action may also have a server-side effect that mirrors what just happened in the browser (for example, updating a server-side "enabled" flag after the client has disabled the element). The mirror is applied during the same server cycle that processes the trigger event, before any user-attached DOM event listeners run, so listener code sees the post-action state.

The same Action instance may be wired to multiple triggers on the same host; the client-side handler runs once per binding.

Implementations should extend AbstractAction.
