java.applet

## Interface AppletStub

-     public interface AppletStub

  When an applet is first created, an applet stub is attached to it using the applet's `setStub` method. This stub serves as the interface between the applet and the browser environment or applet viewer environment in which the application is running.
  Since:
    JDK1.0
  See Also:
    `Applet.setStub(java.applet.AppletStub)`

    `boolean` | `isActive()` Determines if the applet is active.

- - ### Method Detail

    - #### isActive

          boolean isActive()

      Determines if the applet is active. An applet is active just before its `start` method is called. It becomes inactive just before its `stop` method is called.
      Returns:
        `true` if the applet is active; `false` otherwise.

    - #### getDocumentBase

          URL getDocumentBase()

      Gets the URL of the document in which the applet is embedded. For example, suppose an applet is contained within the document:

      >         http://www.oracle.com/technetwork/java/index.html

      The document base is:

      >         http://www.oracle.com/technetwork/java/index.html

      Returns:
        the `URL` of the document that contains the applet.
      See Also:
        `getCodeBase()`

    - #### getCodeBase

          URL getCodeBase()

      Gets the base URL. This is the URL of the directory which contains the applet.
      Returns:
        the base `URL` of the directory which contains the applet.
      See Also:
        `getDocumentBase()`

    - #### getParameter

          String getParameter(String name)

      Returns the value of the named parameter in the HTML tag. For example, if an applet is specified as

      >      <applet code="Clock" width=50 height=50>
      >      <param name=Color value="blue">
      >      </applet>

      then a call to `getParameter("Color")` returns the value `"blue"`.

      Parameters:
        `name` - a parameter name.
      Returns:
        the value of the named parameter, or `null` if not set.

    - #### getAppletContext

          AppletContext getAppletContext()

      Returns the applet's context.
      Returns:
        the applet's context.

    - #### appletResize

          void appletResize(int width,
                            int height)

      Called when the applet wants to be resized.
      Parameters:
        `width` - the new requested width for the applet.
        `height` - the new requested height for the applet.
