Interface PropertyFactory

All Superinterfaces:

PortletService

public interface PropertyFactory
extends PortletService

An factory interface provided by the Property Broker. It provides methods for creation of PropertyController, PropertyValue, ActionController and ParameterController objects.

The PropertyFactory interface is implemented by a PortletService. A portlet can obtain the service by using JNDI. A boolean guard may be used to guard uses of the PropertyFactory by the portlet; this will enable the portlet to execute correctly in JSR-168 compliant portlet containers outside of WebSphere Portal. A snippet of the JNDI lookup code:


boolean propertyFactoryAvailable = false;
PropertyFactory propertyFactory = null;

try {
Context ctx = new InitialContext();
PortletServiceHome serviceHome = (PortletServiceHome) ctx.lookup("portletservice/com.ibm.portal.propertybroker.service.PropertyFactory");
propertyFactory = (PropertyFactory)serviceHome.getPortletService(com.ibm.portal.propertybroker.service.PropertyFactory.class);
propertyFactoryAvailable = true;
}
catch(Throwable t) {
}
A similar interface, com.ibm.wps.pb.property.PropertyFactory is available for use by portlets written to IBM's portlet API.

Since:

5.1.0.1

Method Detail

createPropertyValue

PropertyValue createPropertyValue(javax.portlet.PortletRequest request,
                                  Property property,
                                  java.lang.Object value)
                                  throws CreateFailedException,
                                         AccessFailedException

Creates and returns a PropertyValue. PropertyValue encapsulates a Property with its value.

Parameters:

request - the current portlet request. Must not be null.

property - the Property to be encapsulated in the returned object. Must not be null.

value - the value to be encapsulated in the returned object. May be null.

Returns:

a PropertyValue object encapsulating the information passed in

Throws:

CreateFailedException

AccessFailedException

PropertyValue createPropertyValue(javax.portlet.PortletRequest request,
                                  Property property,
                                  java.lang.Object value,

                                         AccessFailedException

Creates and returns a PropertyValue with a change reason code. PropertyValue encapsulates a Property with its value and a reason the value changed.

Parameters:

request - the current portlet request. Must not be null.

property - the Property to be encapsulated in the returned object. Must not be null.

value - the value to be encapsulated in the returned object. May be null.

changeType - the reason the property value changed

Returns:

a PropertyValue object encapsulating the information passed in

Throws:

CreateFailedException

AccessFailedException

PropertyValue

createProperty

PropertyController createProperty(javax.portlet.PortletRequest request)
                                  throws CreateFailedException

Creates and returns a property associated with a portlet, given the PortletRequest. PropertyController has setters which allow various attribute values to be set.

Parameters:

request - the PortletRequest object. Must not be null.

Returns:

the new PropertyController object created for this portlet

Throws:

CreateFailedException - if the property cannot be created

Property, PropertyController

createProperty

PropertyController createProperty(javax.portlet.PortletConfig config)
                                  throws CreateFailedException

Creates and returns a property associated with a portlet, given the PortletConfig. PropertyController has setters which allow various attribute values for the property to be set. This will be typically done during the portlet's init() method.

Parameters:

config - the PortletConfig object. Must not be null.

Returns:

the new PropertyController object created for this portlet

Throws:

CreateFailedException - if the property cannot be created

Property, PropertyController

createAction

ActionController createAction(javax.portlet.PortletRequest request)
                              throws CreateFailedException

Creates and returns an action associated with a portlet, given the PortletRequest. ActionController has setters which allow various attribute values of the action to be set.

Parameters:

request - the PortletRequest object. Must not be null

Returns:

the new ActionController object created for this portlet

Throws:

CreateFailedException - if the action cannot be created

ActionController createAction(javax.portlet.PortletConfig config)
                              throws CreateFailedException

Creates and returns an action associated with a portlet, given the PortletConfig. ActionController has setters which allow various attribute values of the action to be set. This will be typically done during the portlet's init() method.

                                    throws CreateFailedException

Creates and returns a parameter associated with a portlet's action. This will be typically done during the portlet's init() method. Setter methods may be invoked on the returned ParameterController to modify any attributes of the parameter prior to registering the action.

Parameters:
