Constructor Detail

CPageNode

public CPageNode(CPageSignifPath parentpath,
                 java.lang.String significantpath)

creates a page node

Parameters:

parentpath - parent path for the node

significantpath - if this node has a significant path, a non null string

CPageNode

public CPageNode(MessageReader reader,
                 CPageSignifPath parentpath)
          throws OLcRemoteException,
                 java.io.IOException

Parameters:

reader - message reader

parentpath - parent path element

Throws:

OLcRemoteException - if anything bad happens on the server

java.io.IOException - if anything bad happens during the transmission

Method Detail

setPageCatelog

public static void setPageCatelog(CPageNodeCatalog catalog)

before using the CPageNode methods, especially the static method parseNode

Parameters:

catalog - the widget catalog to use.

deepcopyWithCallback

public abstract CPageNode deepcopyWithCallback(Callback callback)

Parameters:

callback - the callback method, may be null

Returns:

a deep copy of the CPageNode with callback specified set

getNode

public abstract javafx.scene.Node getNode(PageActionManager actionmanager,
                                          CPageData inputdata,
                                          javafx.stage.Window parentwindow,
                                          javafx.scene.control.TabPane[] parenttabpanes)

Parameters:

actionmanager - the action manager on which to register all widgets that trigger an action

inputdata - the list of input data of the page

parentwindow - the javafx window this widget will be drawn in

parenttabpanes - parenttabpanes that should be triggered a layout when this component resizes

Returns:

a displayable node (in JAVAFX)

getDataElt

public abstract DataElt getDataElt(DataEltType type,
                                   java.lang.String eltname,
                                   java.lang.String objectdataloc)

Returns a filled data element of the specified data element type. If there is a format mismatch, an exception is thrown

Parameters:

type - requested type (will be tested by the widget to see if valid)

eltname - the name that will be put to the data element

objectdataloc -

Returns:

getParentpath

public CPageSignifPath getParentpath()

Returns:

parent path to the node (the path is used to link widgets (nodes) and data

getPath

public CPageSignifPath getPath()

Returns:

the path of this element

getSignificantpath

public java.lang.String getSignificantpath()

Returns:

the string output of the significant path of this node (element in the path, equivalent to current folder name)

parseNode

public static CPageNode parseNode(MessageReader reader,
                                  CPageSignifPath parentpath)
                           throws OLcRemoteException,
                                  java.io.IOException

Parameters:

reader - reader

parentpath - path element

Returns:

the parsed page node

Throws:

OLcRemoteException - if anything bad happens on the server

java.io.IOException - if anything bad happens during the transmission

forceUpdateData

public abstract void forceUpdateData(DataElt dataelt)

Parameters:

dataelt - adds data element to the node

mothball

public abstract void mothball()

cleans the page node. Due to the complex structure, some unlinking of different classes is needed to facilitate garbage collection after page is discarded
