netscape.plugin.Plugin
The public class Plugin extends Object. java.lang.Object|
+----netscape.plugin.Plugin This class represents the Java reflection of a plug-in. Plug-ins that need to have Java methods associated with them should subclass this class and add new (possibly native) methods to it. This allows other Java entities (such as applets and JavaScript code) to manipulate the plug-in.

getPeer
Method. Returns the native NPP object--the plug-in instance that is the native part of a Java Plugin object. This field is set by the system, but can be read from plug-in native methods by calling:
NPP npp = (NPP)netscape_plugin_Plugin_getPeer(env, thisPlugin);
Declaration
public int getPeer()
getWindow
Method. Returns the JavaScript window on which the plug-in is embedded.
Declaration
public JSObject getWindow()
init
Method. Called when the plug-in is initialized. You never need to call this method directly, it is called when the plug-in is created.
Declaration
public void init()

destroy
isActive

Declaration
public boolean isActive()
