getPlaceholderPresentationContext(HttpServletRequest) Method
public static PlaceholderPresentationContext
getPlaceholderPresentationContext(HttpServletRequest
request)
This is a convenience method for returning a reference to the one and only PlaceholderPresentationContext for a
given Placeholder
portal component. Note this method will only work if called from within a portal
(typically, from within a *layout.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 PlaceholderPresentationContext, if any

portal component.

portal component. The width attribute
can be used to set the width of a <td> HTML element within a layout JSP, for example.
Returns
- The value of the width attribute, if any
isUsingFlow() Method
public boolean isUsingFlow()
Returns the value of the isUsingFlow attribute for this Placeholder
portal component. If true,

will be used within this Placeholder
to manage its contents.
Returns
- The value of the isUsingFlow attribute; if unspecified, defaults to true
