Method Detail

getComponentStateToSave

protected Object getComponentStateToSave(FacesContext facesContext)

Specified by:

getComponentStateToSave in class StateManager

getTreeStructureToSave

protected Object getTreeStructureToSave(FacesContext facesContext)

Return an object which contains info about the UIComponent type of each node in the view tree. This allows an identical UIComponent tree to be recreated later, though all the components will have just default values for their members.

Specified by:

getTreeStructureToSave in class StateManager

restoreComponentState

protected void restoreComponentState(FacesContext facesContext,
                                     UIViewRoot uiViewRoot,
                                     String renderKitId)

Given a tree of UIComponent objects created the default constructor for each node, retrieve saved state info (from either the client or the server) and walk the tree restoring the members of each node from the saved state information.

Specified by:

restoreComponentState in class StateManager

restoreTreeStructure

protected UIViewRoot restoreTreeStructure(FacesContext facesContext,
                                          String viewId,
                                          String renderKitId)

See getTreeStructureToSave.

Specified by:

restoreTreeStructure in class StateManager

restoreView

public UIViewRoot restoreView(FacesContext facescontext,
                              String viewId,
                              String renderKitId)

Specified by:

restoreView in class StateManager

saveSerializedView

public StateManager.SerializedView saveSerializedView(FacesContext facesContext)
                                               throws IllegalStateException

Specified by:

saveSerializedView in class StateManager

Throws:

IllegalStateException

writeState

public void writeState(FacesContext facesContext,
                       StateManager.SerializedView serializedView)
                throws IOException

Specified by:

writeState in class StateManager

Throws:

IOException

writeStateAsUrlParams

public void writeStateAsUrlParams(FacesContext facesContext,
                                  StateManager.SerializedView serializedView)
                           throws IOException
