Method Details

createComponent

public X3DComponent createComponent(Map<String,Object> params)
                             throws NotSupportedException

Description copied from interface: BrowserFactoryImpl

Create a VRML browser that can be used as an AWT component. The component returned is guaranteed to be an instance of X3DComponent.

Specified by:

createComponent in interface BrowserFactoryImpl

Parameters:

params - Parameters to control the look and feel.

Returns:

The component browser initialised to be empty.

Throws:

NotSupportedException - The implementation does not support this type of browser.

getBrowser

public ExternalBrowser getBrowser(Applet applet)
                           throws NotSupportedException,
NoSuchBrowserException,
ConnectionException

Description copied from interface: BrowserFactoryImpl

Get a browser from the given java applet reference as a base in the current HTML page. Used when attempting to access a browser on the current page as this applet and is the first browser on the page. Generically, the same as calling getBrowser(applet, "", 0);

Specified by:

getBrowser in interface BrowserFactoryImpl

Parameters:

applet - The applet reference to use

Returns:

A reference to the Browser implementation

Throws:

NotSupportedException - The implementation does not support this type of VRML browser

NoSuchBrowserException - Could not locate a VRML browser on the same page as the applet.

ConnectionException - An error occurred during the connecting process

getBrowser

public ExternalBrowser getBrowser(Applet applet,
 String frameName,
 int index)
                           throws NotSupportedException,
NoSuchBrowserException,
ConnectionException

Description copied from interface: BrowserFactoryImpl

Get a browser from the given java applet reference one some named page and at some embed location. Used when attempting to access a browser on another HTML page within a multi-framed environment, or if there are a number of VRML browser instances located on the same page.

If the frame name is a zero length string or null then it is assumed to be located on the same HTML page as the applet. The index is the number of the embed VRML browser starting from the top of the page. If there are other non-VRML plugins embedded in the page these are not taken into account in calculating the embed index.

Specified by:

getBrowser in interface BrowserFactoryImpl

Parameters:

applet - The applet reference to use

frameName - The name of the frame to look into for the browser

index - The embed index of the VRML browser in the page

Returns:

A reference to the Browser implementation

Throws:

NotSupportedException - The implementation does not support this type of VRML browser.

NoSuchBrowserException - Could not locate a VRML browser on the same page as the applet.

ConnectionException - An error occurred during the connecting process

getBrowser

public ExternalBrowser getBrowser(InetAddress address,
 int port)
                           throws NotSupportedException,
NoSuchBrowserException,
UnknownHostException,
ConnectionException

Description copied from interface: BrowserFactoryImpl

Get a reference to a browser that is located on a remote machine. This a server application to send scene updates to a number of client browsers located on remote machines. If there are a number of browsers running on a remote machine, they can be differentiated by the port number they are listening on.

There is no default port number for VRML browsers.

Specified by:

getBrowser in interface BrowserFactoryImpl

Parameters:

address - The address of the machine to connect to

port - The port number on that machine to connect to.

Returns:

A reference to the Browser implementation

Throws:

UnknownHostException

NotSupportedException - The implementation does not support this type of VRML browser.

NoSuchBrowserException - Could not locate a VRML browser on the same page as the applet.

ConnectionException - An error occurred during the connecting process

getBrowser

public ExternalBrowser getBrowser()

Description copied from interface: X3DComponent

Get a browser reference from this component that represents the internals of this browser.

Specified by:

getBrowser in interface X3DComponent

Returns:

A reference to the browser object represented by this component.

See Also:

• X3DComponent.getBrowser()

getImplementation

public Object getImplementation()

Description copied from interface: X3DComponent

Get a reference to the component implementation. For example, if this is an AWT component, it would return an instance of Component.

Specified by:

getImplementation in interface X3DComponent

Returns:

a reference to the component implementation

See Also:

• X3DComponent.getImplementation()

shutdown

public void shutdown()

Description copied from interface: X3DComponent
