@Deprecated(since="9", forRemoval=true) public interface AppletContext
The methods in this interface can be used by an applet to obtain information about its environment.
Modifier and Type | Method | Description |
---|---|---|
Applet |
getApplet |
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. |
Enumeration |
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. |
AudioClip |
getAudioClip |
Deprecated, for removal: This API element is subject to removal in a future version. Creates an audio clip. |
Image |
getImage |
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. |
InputStream |
getStream |
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. |
Iterator |
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. |
void |
setStream |
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. |
void |
showDocument |
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. |
void |
showDocument |
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. |
void |
showStatus |
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". |
AudioClip getAudioClip(URL url)
url
- an absolute URL
giving the location of the audio clipURL
Image getImage(URL url)
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.
url
- an absolute URL
giving the location of the imageURL
Applet getApplet(String name)
name
attribute.name
- an applet namenull
if not foundEnumeration<Applet> getApplets()
void showDocument(URL url)
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.url
- an absolute URL
giving the location of the documentvoid showDocument(URL url, String target)
url
argument. The target
argument indicates in which HTML frame the document is to be displayed. The target argument is interpreted as follows: 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
.

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
key
- key with which the specified value is to be associatedstream
- stream to be associated with the specified key. If this parameter is null
, the specified key is removed in this applet context.IOException
- if the stream size exceeds a certain size limit. Size limit is decided by the implementor of this interface.InputStream getStream(String key)
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.

- key whose associated stream is to be returnedIterator<String> getStreamKeys()

Iterator
of all the names of the streams in this applet context
