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.
