public class HyperLinkWrapper
extends VBean
implements ActionListener

Oracle Forms Server 6i JavaBean Example

This class acts as a wrapper around the HyperLink JavaBean, enabling it to be embedded and enclosed within an Oracle Forms application. The Oracle Forms application will call the methods on this class which in turn delegates them, performing type translation if necessary onto the HyperLink JavaBean it has instantiated. This class should be embedded within an Oracle Forms application inside of a BeanArea item and the implementation class should be set to oracle.forms.demos.HyperLinkWrapper.

Constructors

o HyperLinkWrapper 
 public HyperLinkWrapper()
Create a HyperLinkWrapper which acts as a wrapper around a HyperLink component and allows it to function within Oracle Forms.

Methods

o init 
 public void init(IHandler handler)
IView initialisation method for this component, will be called when Forms creates a new item instance.

Parameters:
the - Forms Handler object for this view class
Overrides:
init in class VBean
o getProperty 
 public Object getProperty(ID id)
Overriding method from the IView interface. Allows the values of properties to be retrieved when called from the Oracle Forms Server runtime. This method allows the Forms Server to get both standard and custom properties. The standard properties such as FOREGROUND, FONT, etc. all have type mappings performed by the Forms engine itself so these can simply be passed from their analog accessor methods on the JavaBean. For the custom properties, sometimes type translation is required since Forms will only allow a String type as a return value for a custom property.

Parameters:
id - the property to be retrieved, identified by it's ID
Returns:
Object the value of the requested property
Overrides:
getProperty in class VBean
o setProperty 
 public boolean setProperty(ID id,
                            Object value)

Parameters:
id - the property to be retrieved, identified by it's ID
Returns:

Overrides:

o actionPerformed 
 public void actionPerformed(ActionEvent ae)
Notified when the HyperLink Label is clicked by a user indicating that the link has been 'followed'.

Parameters:
ae - ActionEvent with details of the link that has been clicked
o log 
 public void log(String msg)
Debug facility to output message in a standard format if the DEBUG attribute is set to TRUE.

Parameters:
msg - The message to be output
