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 Summary
`protected` | `PortletPresentationContext()`

Method Summary
`String` | `getInstanceLabel()` Return the instance label for the portlet.
`String` | `getLabel()` Return the unique label for the portlet.
`static PortletPresentationContext` | `getPortletPresentationContext(HttpServletRequest request)` This is a convenience method for returning a reference to the current `PortletPresentationContext`.
`String` | `getPortletUri()` Getter for the portlet's URI.
`PortletPreferences` | `getPreferences(HttpServletRequest request)` Returns a read-only copy of preferences for this portlet.
`boolean` | `isCapable(Capability capability)` Returns `true` if this control has the specified capability.
`boolean` | `isDefaultMinimized()` Returns the value for `defaultMinimized`.``

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

### getPortletUri

    public String getPortletUri()

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

  Returns:
    A String containing the portlets uri.

### isDefaultMinimized

    public boolean isDefaultMinimized()

  Returns the value for `defaultMinimized`.

  ``

### 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

### 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
  See Also:
    `WindowCapabilities`
