Class TLcyKML22TreeModelObject

java.lang.Object

com.luciad.lucy.addons.kml22.TLcyKML22TreeModelObject

public class TLcyKML22TreeModelObject
extends Object

Represents a tree model object.

This class is used by the JTree created by the default TLcyKML22GUIFactory of the TLcyKML22AddOn

A tree model object acts a wrapper around an object that is part of the KML hierarchy. This object can be retrieved through the getTreeModelObject() method. An instance of this class also contains information on the model, layer and view that contain the object.

Since:

10.0

TLcyKML22TreeModelObject

public TLcyKML22TreeModelObject(Object aTreeModelObject,
 ILcdModel aModel,
 ILcdLayer aLayer,
 ILcdView aView)

Creates a new tree model object

Parameters:

aTreeModelObject - A tree model object. See getTreeModelObject() for more information.

aModel - A model that is directly contained by aLayer. This is always an instance of TLcdKML22RenderableModel

aLayer - A KML layer

aView - A view that directly contains aLayer

TLcyKML22TreeModelObject

public TLcyKML22TreeModelObject(Object aTreeModelObject,
 ILcdModel aModel,
 ILcdLayer aLayer,
 ILcdView aView,
 TLcyKML22TreeModelObject aParent)

Creates a new tree model object with given parent.

Parameters:

aTreeModelObject - A tree model object. See getTreeModelObject() for more information.

aModel - A model that is directly contained by aLayer. This is always an instance of TLcdKML22RenderableModel

aLayer - A KML layer

aView - A view that directly contains aLayer

aParent - The parent node of this TLcyKML22TreeModelObject

Method Details

getTreeModelObject

public Object getTreeModelObject()

Returns an object that represents an element in the model content tree of KML.

This is always one of the following:

• TLcdKML22DynamicModel for all non-leaf elements, such as KML containers.
• TLcdKML22PaintableGroundOverlay for all leaf-elements that represent GroundOverlays.
• TLcdKML22AbstractFeature for all other leaf elements.

Returns:

a tree model object

getLayer

public ILcdLayer getLayer()

Returns a layer that has the following properties:

• It is contained by the ILcdView returned by getView()
• It contains the ILcdModel returned by getModel()

Returns:

a KML layer

getModel

public ILcdModel getModel()

Returns a layer that has the following properties:

• It is contained by the ILcdLayer returned by getLayer() ()}
• It contains the tree model object returned by getTreeModelObject() somewhere in its underlying hierarchy

Returns:

a KML layer

getView

public ILcdView getView()

Returns a layer that has the following properties:

• It contains the ILcdLyaer returned by getLayer() ()}

Returns:

a KML layer

getParent

public TLcyKML22TreeModelObject getParent()

Returns the parent of this TLcyKML22TreeModelObject

Returns:

The parent of this TLcyKML22TreeModelObject; null if this node is the root node and has no parent.

getChildren

public List<TLcyKML22TreeModelObject> getChildren()

Gets the children of this TLcyKML22TreeModelObject

If a child is added or removed, this list should be updated as well

Returns:

the children of this TLcyKML22TreeModelObject

addModelNodeContainerListener

public void addModelNodeContainerListener(ILcdModelContainerListener aModelContainerListener)

Adds a ILCdModelContainerListener to this TLcyKML22TreeModelObject. The model container listener will be given ModelNodeContainerEvent instances.

Parameters:

aModelContainerListener - a model container listener

removeModelNodeContainerListener

public void removeModelNodeContainerListener(ILcdModelContainerListener aModelContainerListener)

Removes a ILcdModelContainerListener from this TLcyKML22TreeModelObject.

Parameters:

aModelContainerListener - a model container listener

• addModelNodeContainerListener(com.luciad.model.ILcdModelContainerListener)

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

destroy

public void destroy()

Destroys this tree model object by removing all internal state. The tree model object is no longer valid after this call.
