Class JsDefinitionProxy

java.lang.Object

com.vaadin.flow.js.JsDefinitionProxy

public final class JsDefinitionProxy
extends Object

Hands out implementations of JsDefinition interfaces, which turn a call of a declared method into a JsCall and give it to whoever runs it.

The interface is checked here rather than when a method is called, so one that can not work says so when the implementation is handed out.

For internal use only. Call Element.executeJs(Class), which runs the call on the element the implementation was obtained from.

Since:

25.4
