Method Detail

### getHeadPresentationContext

    public static HeadPresentationContext getHeadPresentationContext(HttpServletRequest request)

  This is a convenience method for returning a reference to the one and only `HeadPresentationContext`. Note this method will only work if called from within a portal (typically, from the head.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 HeadPresentationContext, if any
