Class TLcdModelTreeNodeSupport

java.lang.Object

com.luciad.model.TLcdModelTreeNodeSupport

All Implemented Interfaces:

ILcdModelContainer, ILcdModelProducerListener, EventListener

public class TLcdModelTreeNodeSupport
extends Object
implements ILcdModelContainer

This is a utility class that can be used to create an ILcdModelTreeNode implementation. This utility class provides support for all the methods in ILcdModelTreeNode which are not inherited from ILcdModel.

As a consequence, this class is ideal for creating ILcdModelTreeNode implementations based on an existing ILcdModel implementation. All those ILcdModelTreeNode methods can then be delegated to an instance of this class.

Since:

9.0

Constructor Details

TLcdModelTreeNodeSupport

public TLcdModelTreeNodeSupport(ILcdModelTreeNode aNode)

Creates a new support object for node aNode

Parameters:

aNode - the node for which a support object is needed

Method Details

addModel

public boolean addModel(ILcdModel aModel)

Add a new model to the container, and add the hierarchy listeners to it in order to be informed of all the events in the newly added model

Specified by:

addModel in interface ILcdModelContainer

Parameters:

aModel - the model to be added.

Returns:

true if this collection of models changed as a result of the call

removeModel

public boolean removeModel(ILcdModel aModel)

Remove a model from the container, and remove all the hierarchy listeners which were added

Specified by:

removeModel in interface ILcdModelContainer

Parameters:

aModel - the model to be removed.

Returns:

true if a model was removed as a result of this call

addHierarchyModelContainerListener

public void addHierarchyModelContainerListener(ILcdModelContainerListener aModelContainerListener)

Registers the given ILcdModelContainerListener to receive TLcdModelContainerEvents from all the ILcdModelTreeNodes contained in the tree with this node as root node.

The source ILcdModelContainer of the event can be retrieved by calling TLcdModelContainerEvent.getModelContainer() on the received TLcdModelContainerEvent.

Parameters:

aModelContainerListener - the listener

• removeHierarchyModelContainerListener(ILcdModelContainerListener)

removeHierarchyModelContainerListener

public void removeHierarchyModelContainerListener(ILcdModelContainerListener aModelContainerListener)

Unregisters the given ILcdModelContainerListener from receiving TLcdModelContainerEvents for the tree with the node for which this support is responsible as root node.

Parameters:

aModelContainerListener - the listener, must not be null

See Also:

• addHierarchyModelContainerListener(ILcdModelContainerListener)

addHierarchyModelListener

public void addHierarchyModelListener(ILcdModelListener aModelListener)

Registers the given ILcdModelListener to receive TLcdModelChangedEvents from all the ILcdModels contained in the tree with this node as root node.

The source ILcdModel of the event can be retrieved by calling TLcdModelChangedEvent.getModel() on the received TLcdModelChangedEvent.

Parameters:

aModelListener - the listener

See Also:

• removeHierarchyModelListener(ILcdModelListener)

removeHierarchyModelListener

public void removeHierarchyModelListener(ILcdModelListener aModelListener)
