Package com.vaadin.flow.i18n

Class DefaultTranslationsHotswapper

java.lang.Object

com.vaadin.flow.i18n.DefaultTranslationsHotswapper

All Implemented Interfaces:

VaadinHotswapper

public class DefaultTranslationsHotswapper
extends Object
implements VaadinHotswapper

Handles the automatic hotswapping of translation resources in a Vaadin-based application. This class listens for changes in application resources and takes appropriate actions to update related translations dynamically.

When a resource file matching the path pattern for translation properties (e.g., `vaadin-i18n/*.properties`) is changed, this class performs two main actions: 1. Clears the ResourceBundle cache to ensure the latest translations are loaded. 2. Notifies the client about the translation updates by triggering an appropriate update event and UI refreshes.

For internal use only. May be renamed or removed in a future release.

Since:

25.0
