Interface Portlet

All Superinterfaces:

Identifiable, Localized, MarkupCapable, MetaDataProvider, PortletPreferencesProvider

All Known Subinterfaces:

ModifiablePortlet

public interface Portlet
extends Identifiable, MarkupCapable, PortletPreferencesProvider, Localized

Interface that represents the deployed code unit for a portlet, as specified in the deployment descriptor. Properties of the portlet are defined by the portlet programmer and deployer, typically in the deployment descriptor, and cannot be altered after deployment.

All methods that take or return supported markups as strings will also accept or return mimetype strings. For example, for a portlet supporting the html markup, both supportsMarkup("html") and supportsMarkup("text/html") will return true. The supported mimetypes must not contain a character set definition and must not contain wildcards.

Since:

6.0.1

supportsPortletMode

boolean supportsPortletMode(PortletMode mode)
                            throws ModelException

Checks if a given portlet mode is in the list of supported portlet modes.
This method checks if the portlet may be invoked in the given mode in any of its supported markups.

Parameters:

mode - The portlet mode that is to be checked.

Returns:

true if the mode is in the list of supported modes for any supported markup, false if not.

Throws:

ModelException - in case the portlet modes cannot be obtained

supportsPortletMode

                            throws ModelException

Checks if a given portlet mode is in the list of supported portlet modes for the given markup.
This method checks if the portlet may be invoked in the given mode in the given markup, which must be in the list of supported markups for the portlet

Parameters:

mode - The portlet mode that is to be checked.

markup - The markup for which the mode is to be checked.

Returns:

true if the markup is in the list of supported markups and the mode is in the list of supported modes for that markup, false if not.
