Class Browser

  • public class Browser
extends java.lang.Object
    Contains the API for calling JavaScript functions using TeaVM. This consists of general browser APIs, as well as drawing operations for the HTML5 canvas that is displaying the application.

    Note for testing: All methods in this class are defined as static native due to requirements from TeaVM. Applications should therefore mock these methods when using the browser API in Java unit tests.
