public class KMLNetworkLinkTreeNode
extends KMLContainerTreeNode

A KMLFeatureTreeNode that represents a KML network link defined by a KMLNetworkLink.

KMLNetworkLinkTreeNode automatically repopulates its hierarchy when its KMLNetworkLink is refreshed, and notifies its listeners when this happens.

Constructor Detail

KMLNetworkLinkTreeNode

public KMLNetworkLinkTreeNode(KMLNetworkLink networkLink)

Creates a new KMLNetworkLinkTreeNode from the specified networkLink. The node's name is set to the network link's name, and the node's hierarchy is populated from the network link's KML features.

Parameters:

networkLink - the KML network link this node represents.

Throws:

java.lang.IllegalArgumentException - if the networkLink is null.

Method Detail

getFeature

public KMLNetworkLink getFeature()

Indicates the KML network link this node represents.

Overrides:

getFeature in class KMLContainerTreeNode

Returns:

this node's KML network link.

initialize

protected void initialize()

Places the KML feature in the node's AVKey.CONTEXT field.

Additionally, this node's hierarchy is populated from the KML features in its KMLNetworkLink, and this registers a RETRIEVAL_STATE_SUCCESSFUL property change listener on the KMLNetworkLink.

Overrides:

initialize in class KMLContainerTreeNode

refresh

protected void refresh()

Called when this node's KMLNetworkLink refreshes. Clears this node's hierarchy by removing its children, then adds a new KMLFeatureTreeNode to this node for each KML feature in the KMLNetworkLink.

If the KMLNetworkLink's top level feature is a KMLDocument, this method ignores the document and adds its children directly to this node. Creating a node for the document adds an extra level to the tree node that doesn't provide any meaningful grouping.

Overrides:

refresh in class KMLContainerTreeNode
