AppletContext

Fields Summary

Constructors Summary

Methods Summary
public java.applet.Applet	getApplet(java.lang.String name) 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. param name an applet name. return the applet with the given name, or null if not found.
public java.util.Enumeration	getApplets() Finds all the applets in the document represented by this applet context. return an enumeration of all applets in the document represented by this applet context.
public java.applet.AudioClip	getAudioClip(java.net.URL url) Creates an audio clip. param url an absolute URL giving the location of the audio clip. return the audio clip at the specified URL.
public java.awt.Image	getImage(java.net.URL url) 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. param url an absolute URL giving the location of the image. return the image at the specified URL. see java.awt.Image
public java.io.InputStream	getStream(java.lang.String key) 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 return the stream to which this applet context maps the key param key key whose associated stream is to be returned. since 1.4
public java.util.Iterator	getStreamKeys() 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 return an Iterator of all the names of the streams in this applet context. since 1.4
public void	setStream(java.lang.String key, java.io.InputStream stream) 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 param key key with which the specified value is to be associated. param 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
public void	showDocument(java.net.URL url) 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. param url an absolute URL giving the location of the document.
public void	showDocument(java.net.URL url, java.lang.String target) 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 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. param url an absolute URL giving the location of the document. param target a String indicating where to display the page.
public void	showStatus(java.lang.String status) 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. param status a string to display in the status window.
