All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.image.ImageObserver, java.awt.MenuContainer, javax.swing.RootPaneContainer, java.io.Serializable

Direct Known Subclasses:

SampleApplet, SampleApplet

public abstract class EApplet

extends javax.swing.JApplet

This class must be subclassed by all bankframe frontends which must implement the necessary methods.

This class provides methods to:

1. get the host from which the client must communicate to, i.e. the getHost() method.
2. set and get the initial data received from the main() method.
3. load the applications icons.
4. close the application if run as an application, i.e. the close() method.

It also provides an abtract init() method that must be implemented by subclasses.

Method Detail

close

public void close()

This method will close the Application. It will call the stop() method of the applet and if running as an application call the System.exit() method.

eMain

public static javax.swing.JFrame eMain(java.lang.String title,
                                       EApplet eApplet,
                                       java.awt.Dimension size,
                                       java.lang.String[] args)

This method provides a template method to start an EApplet application.

Parameters:

title - String

eApplet - com.bankframe.fe.ui.EApplet

size - Dimension

args - String[]

getHost

public java.net.URL getHost()

This method determines the host location of the server. If run as an application, it retrieves the HTTP_SERVER value from BankFrameResource.properties. If run as an applet the .properties files must be included in the jar that contains the example classes.

Returns:

the URL ofthe host.

getInitialData

public java.lang.String[] getInitialData()

This method returns the initial data of the applet.

Returns:

the initial data

getJFrame

public static javax.swing.JFrame getJFrame(java.awt.Container c)

This method finds the JFrame instance that a container is on.

Parameters:

c - Container

Returns:

JFrame

init

public abstract void init()

This method initializes the applet/application. It must be implemented by the subclasses of this class. Primarily it should create an instance of the applications EAppletContainer. For example a subclass may implement this method to invoke the EAppletContainer as follows:

public void init() {
this.setEPanelContainer(new TellerEPanelContainer(this, new EHTTPCommsManager("HTTP", this.getHost())));
}


loadImages

public void loadImages()

This method loads the application's icons using the ApplicationIcons class. The icons or images for the application are held as class variables that can be accessed by any class once the icons are loaded.
