# Interface AppletContext

@Deprecated(since="9", forRemoval=true) public interface AppletContext
Deprecated, for removal: This API element is subject to removal in a future version.
The Applet API is deprecated, no replacement.
This interface corresponds to an applet's environment: the document containing the applet and the other applets in the same document.

The methods in this interface can be used by an applet to obtain information about its environment.

Since:
  1.0

## Method Details

### getAudioClip

AudioClip getAudioClip(URL url)
Deprecated, for removal: This API element is subject to removal in a future version.
Creates an audio clip.

Parameters:
  `url` - an absolute `URL` giving the location of the audio clip
Returns:
  the audio clip at the specified `URL`

### getImage

Image getImage(URL url)
Deprecated, for removal: This API element is subject to removal in a future version.
Returns an `Image` object that can then be painted on the screen. The `url` argument that is passed as an argument must specify an absolute `URL`.

This method always returns immediately, whether or not the image exists. When the applet attempts to draw the image on the screen, the data will be loaded. The graphics primitives that draw the image will incrementally paint on the screen.

Parameters:
  `url` - an absolute `URL` giving the location of the image
Returns:
  the image at the specified `URL`
See Also:
  - `Image`

### getApplet

Applet getApplet(String name)
Deprecated, for removal: This API element is subject to removal in a future version.
Finds and returns the applet in the document represented by this applet context with the given name. The name can be set in the HTML tag by setting the `name` attribute.

Parameters:
  `name` - an applet name
Returns:
  the applet with the given name, or `null` if not found

### getApplets

Enumeration<Applet> getApplets()
Deprecated, for removal: This API element is subject to removal in a future version.
Finds all the applets in the document represented by this applet context.

Returns:
  an enumeration of all applets in the document represented by this applet context

### showDocument

void showDocument(URL url)
Deprecated, for removal: This API element is subject to removal in a future version.
Requests that the browser or applet viewer show the Web page indicated by the `url` argument. The browser or applet viewer determines which window or frame to display the Web page. This method may be ignored by applet contexts that are not browsers.

Parameters:
  `url` - an absolute `URL` giving the location of the document

### showDocument

void showDocument(URL url, String target)
Deprecated, for removal: This API element is subject to removal in a future version.
Requests that the browser or applet viewer show the Web page indicated by the `url` argument. The `target` argument indicates in which HTML frame the document is to be displayed. The target argument is interpreted as follows:

Target arguments and their descriptions
Target Argument | Description
--- | ---
`"_self"` | Show in the window and frame that contain the applet.
`"_parent"` | Show in the applet's parent frame. If the applet's frame has no parent frame, acts the same as "_self".
`"_top"` | Show in the top-level frame of the applet's window. If the applet's frame is the top-level frame, acts the same as "_self".
`"_blank"` | Show in a new, unnamed top-level window.
name | Show in the frame or window named name. If a target named name does not already exist, a new top-level window with the specified name is created, and the document is shown there.

An applet viewer or browser is free to ignore `showDocument`.

Parameters:
  `url` - an absolute `URL` giving the location of the document
  `target` - a `String` indicating where to display the page

### showStatus

void showStatus(String status)
Deprecated, for removal: This API element is subject to removal in a future version.
Requests that the argument string be displayed in the "status window". Many browsers and applet viewers provide such a window, where the application can inform users of its current state.

Parameters:
  `status` - a string to display in the status window

### setStream

void setStream(String key, InputStream stream) throws IOException
Deprecated, for removal: This API element is subject to removal in a future version.
Associates the specified stream with the specified key in this applet context. If the applet context previously contained a mapping for this key, the old value is replaced.

For security reasons, mapping of streams and keys exists for each codebase. In other words, applet from one codebase cannot access the streams created by an applet from a different codebase

Parameters:
  `key` - key with which the specified value is to be associated
  `stream` - stream to be associated with the specified key. If this parameter is `null`, the specified key is removed in this applet context.
Throws:
  `IOException` - if the stream size exceeds a certain size limit. Size limit is decided by the implementor of this interface.
Since:
  1.4

### getStream

InputStream getStream(String key)
Deprecated, for removal: This API element is subject to removal in a future version.
Returns the stream to which specified key is associated within this applet context. Returns `null` if the applet context contains no stream for this key.

For security reasons, mapping of streams and keys exists for each codebase. In other words, applet from one codebase cannot access the streams created by an applet from a different codebase.

Parameters:
  `key` - key whose associated stream is to be returned
Returns:
  the stream to which this applet context maps the key
Since:
  1.4

### getStreamKeys

Iterator<String> getStreamKeys()
Deprecated, for removal: This API element is subject to removal in a future version.
Finds all the keys of the streams in this applet context.

For security reasons, mapping of streams and keys exists for each codebase. In other words, applet from one codebase cannot access the streams created by an applet from a different codebase.

Returns:
  an `Iterator` of all the names of the streams in this applet context
Since:
  1.4
