Interface NavigationalState

All Known Subinterfaces:

MutableNavigationalState

public interface NavigationalState

NavigationalState gives readonly access to the state of the Portal URL and all navigational state context as well as encoding a new State for usage in a Portal URL.
Note: Support for changing the PortletMode and/or WindowState of a PortletWindow, other than for encoding a new State is moved down to the MutableNavigationState interface to cleanly define the immutable contract of this interface.

Parameters:

window -

Returns:

getState

javax.portlet.WindowState getState(String windowId)

Deprecated.

Gets the window state for given portlet window id.

Parameters:

windowId -

Returns:

getMappedState

javax.portlet.WindowState getMappedState(String windowId)

Gets the internal (portal) window state for given portlet window id.

Parameters:

windowId -

Returns:

javax.portlet.PortletMode getMode(PortletWindow window)

Gets the portlet mode for the given portlet window.

Parameters:

window -

Returns:

getMappedMode

javax.portlet.PortletMode getMappedMode(PortletWindow window)

Gets the internal (portal) portlet mode for the given portlet window.

getRequestParameterMap

Map<String,String[]> getRequestParameterMap()

Provides a "safe" copy of the client/portal request parameterMap, with the values already (re)encode in the preferred or requested character encoding

This parameterMap is created early (and only once) to protect against dynamic modification by certain webcontainers like Websphere which might change the contents of the original request parametersMap during request dispatching with additional query string parameters.

Furthermore, when using parallel rendering this is even more critical to do upfront and only once while still in the initial portal request Thread.

Returns:

getParameterMap

Map<String,String[]> getParameterMap(PortletWindow window)

isActionScopedRequestAttributes

boolean isActionScopedRequestAttributes(PortletWindow window)

getActionScopeId

String getActionScopeId(PortletWindow window)

isActionScopeRendered

boolean isActionScopeRendered(PortletWindow window)

getCacheLevel

String getCacheLevel(PortletWindow window)

getResourceID

String getResourceID(PortletWindow window)

getPrivateRenderParameterMap

Map<String,String[]> getPrivateRenderParameterMap(PortletWindow window)

getPublicRenderParameterMap

getPortletWindowOfAction

PortletWindow getPortletWindowOfAction()

getPortletWindowOfResource

PortletWindow getPortletWindowOfResource()

getWindowIdIterator
