Interface PortletConfig

All Known Implementing Classes:

GenericPortlet

public interface PortletConfig

The PortletConfig interface provides the portlet with its configuration. The configuration holds information about the portlet that is valid for all users. The configuration is retrieved from the portlet definition in the deployment descriptor. The portlet can only read the configuration data.

The configuration information contains the portlet name, the portlet initialization parameters, the portlet resource bundle and the portlet application context.

Method Detail

getPortletName

String getPortletName()

Returns the name of the portlet.

The name may be provided via server administration, assigned in the portlet application deployment descriptor with the portlet-name tag.

Returns

the portlet name

getPortletContext

PortletContext getPortletContext()

Returns the PortletContext of the portlet application the portlet is in.

Returns

a PortletContext object, used by the caller to interact with its portlet container

PortletContext

getResourceBundle

ResourceBundle getResourceBundle(Locale locale)

Gets the resource bundle for the given locale based on the resource bundle defined in the deployment descriptor with resource-bundle tag or the inlined resources defined in the deployment descriptor.

Parameters

locale - the locale for which to retrieve the resource bundle

Returns

the resource bundle for the given locale

getInitParameter

String getInitParameter(String name)

Returns a String containing the value of the named initialization parameter, or null if the parameter does not exist.

Parameters

name - a String specifying the name of the initialization parameter

Returns

a String containing the value of the initialization parameter

Throws

IllegalArgumentException - if name is null.

getInitParameterNames

Enumeration<String> getInitParameterNames()

Returns the names of the portlet initialization parameters as an Enumeration of String objects, or an empty Enumeration if the portlet has no initialization parameters.

Returns

an Enumeration of String objects containing the names of the portlet initialization parameters, or an empty Enumeration if the portlet has no initialization parameters.

getPublicRenderParameterNames

Enumeration<String> getPublicRenderParameterNames()

Returns the names of the public render parameters supported by the portlet as an Enumeration of String objects, or an empty Enumeration if the portlet has not defined public render parameters.

Public render parameters are defined in the portlet deployment descriptor with the supported-public-render-parameter element.

Returns

an Enumeration of String objects containing the names of the public render parameters, or an empty Enumeration if the portlet has not defined support for any public render parameters in the portlet deployment descriptor.

Since:

2.0

getDefaultNamespace

String getDefaultNamespace()

Returns the default namespace for events and public render parameters. This namespace is defined in the portlet deployment descriptor with the default-namespace element.

If no default namespace is defined in the portlet deployment descriptor this methods returns the XML default namespace XMLConstants.NULL_NS_URI.

Returns

the default namespace defined in the portlet deployment descriptor, or XMLConstants.NULL_NS_URI is non is defined.

Since:

2.0

getPublishingEventQNames

Enumeration<QName> getPublishingEventQNames()

Returns the QNames of the publishing events supported by the portlet as an Enumeration of QName objects, or an empty Enumeration if the portlet has not defined any publishing events.

Publishing events are defined in the portlet deployment descriptor with the supported-publishing-event element.

Note that this call does not return any events published that have not been declared in the deployment descriptor as supported.

If the event was defined using the name element instead of the qname element the defined default namespace is added as namespace for the returned QName.

Returns

an Enumeration of QName objects containing the names of the publishing events, or an empty Enumeration if the portlet has not defined any support for publishing events in the deployment descriptor.

Since:

2.0

getProcessingEventQNames

Enumeration<QName> getProcessingEventQNames()

Returns the QNames of the processing events supported by the portlet as an Enumeration of QName objects, or an empty Enumeration if the portlet has not defined any processing events.

Processing events are defined in the portlet deployment descriptor with the supported-processing-event element.

If the event was defined using the name element instead of the qname element the defined default namespace is added as namespace for the returned QName.

Returns

an Enumeration of QName objects containing the names of the processing events, or an empty Enumeration if the portlet has not defined any support for processing events in the deployment descriptor.

Since:

2.0

getSupportedLocales

Enumeration<Locale> getSupportedLocales()

Returns the locales supported by the portlet as an Enumeration of Locale objects, or an empty Enumeration if the portlet has not defined any supported locales.

Supported locales are defined in the portlet deployment descriptor with the supported-locale element.

Returns

an Enumeration of Locale objects containing the supported locales, or an empty Enumeration if the portlet has not defined any supported locales in the deployment descriptor.

Since:

2.0

getContainerRuntimeOptions

Map<String,String[]> getContainerRuntimeOptions()

Returns the container runtime options and values for this portlet.

The portlet can set container runtime options in the portlet.xml via the container-runtime-option element with a name and a value on the application and portlet level.
If a container runtime option is set on the portlet application level and on the portlet level with the same name the setting on the portlet level takes precedence and overwrites the one set on the portal application level.

The map returned from this method will provide the subset the portlet container supports of the options the portlet has specified in the portlet.xml. Options that the portlet container does not support will not be returned in this map.

The map will contain name of the runtime option as key of type String and the runtime options as values of type String array (String[]) with the values specified in the portlet.xml deployment descriptor.

Returns

an immutable Map containing portlet container runtime options names as keys and the container runtime values as map values, or an empty Map if no portlet container runtime options are set in the portlet.xml or supported by this portlet container. The keys in the map are of type String. The values in the map are of type String array (String[]).

Since:

2.0
