public class PortletPresentationContext

extends WindowPresentationContext

This class represents a portal portlet component. All presentation-related attributes of a portlet component are available from instances of this class. Such instances are typically used during portal rendering via look and feel skeleton files (e.g. window.jsp).

Depending on the context of invocation of this classes methods, some may throw UnsupportedOperationException. Such contexts include within remote WSRP portlets. All methods should function normally for locally rendered portlets.

Constructor Detail

PortletPresentationContext

protected PortletPresentationContext()

Method Detail

getInstanceLabel

public String getInstanceLabel()

Return the instance label for the portlet. This is a unique identifier for the portlet.

Returns:

The portlet's instance label

getLabel

public String getLabel()

Return the unique label for the portlet. For portlets this is the same as calling getInstanceLabel().

Specified by:

getLabel in class WindowPresentationContext

Returns:

The portlet's unique label

getPagePresentationContext

public PagePresentationContext getPagePresentationContext()

Return the portlets parent PagePresentationContext.

Returns:

If this portlet is placed on a page then a reference to the parent page's backing context, otherwise null.

getPortletPresentationContext

public static PortletPresentationContext getPortletPresentationContext(HttpServletRequest request)

This is a convenience method for returning a reference to the current PortletPresentationContext. Note this method will only work if called from within a portal (typically, from the window.jsp skeleton). This method may return null if called when no appropriate context exists, but such a context should safely exist when being fetched from the associated skeleton JSP during normal portal rendering.

Parameters:

request - The current HTTPServletRequest instance

Returns:

A reference to the current PortletPresentationContext, if any

getPortletUri

public String getPortletUri()

Getter for the portlet's URI. Example: /portlets/myportlet/myportlet.portlet

Returns:

A String containing the portlets uri.

getPreferences

public PortletPreferences getPreferences(HttpServletRequest request)

Returns a read-only copy of preferences for this portlet.

Parameters:

request - The current HTTPServletRequest instance

Returns:

The read-only preferences instance

isCapable

public boolean isCapable(Capability capability)

Returns true if this control has the specified capability.

Overrides:

isCapable in class WindowPresentationContext

Parameters:

capability - A window mode or state

WindowCapabilities

isDefaultMinimized

public boolean isDefaultMinimized()

Returns the value for defaultMinimized.
