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.

Constructors and方法

The netscape.plugin.Plugin class has the following constructors:

表 14.4 Constructors for the Plugin class
Constructor 描述
Plugin Constructs a Plugin.

The netscape.plugin.Plugin class has the following methods:

表 14.5 Methods for the Plugin class
Method 描述
destroy Called when the plug-in is destroyed
getPeer Returns the native NPP object--the plug-in instance that is the native part of a Java Plugin object
getWindow Returns the JavaScript window on which the plug-in is embedded
init Called when the plug-in is initialized
isActive Determines whether the Java reflection of a plug-in still refers to an active plug-in

The following sections show the declaration and usage of these constructors and methods.

destroy

Method. Called when the plug-in is destroyed. You never need to call this method directly, it is called when the plug-in is destroyed. At the point this method is called, the plug-in will still be active.

Declaration

public void destroy()

init

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()

参看

destroy

isActive

Method. Determines whether the Java reflection of a plug-in still refers to an active plug-in. Plug-in instances are destroyed whenever the page containing the plug-in is left, thereby causing the plug-in to no longer be active.

Declaration

public boolean isActive()

Plugin

Constructor. Constructs a Plugin.

Declaration

public Plugin()
