Class SelectedNodesAndEdgesEvent

java.lang.Object

org.cytoscape.event.AbstractCyEvent<CyNetwork>

org.cytoscape.model.events.SelectedNodesAndEdgesEvent

All Implemented Interfaces:

CyEvent<CyNetwork>

public class SelectedNodesAndEdgesEvent
extends AbstractCyEvent<CyNetwork>

Event that signals when the selection state of nodes and/or edges has changed within a network.

This is a convenience API. The traditional way to detect node/edge selection is to use a RowsSetEvent. However that event fires for every change to a table, not just selection change, and requires the listener to map the rows that changed back to nodes and edges. This event provides a more convenient API for listeners that just want to be signaled about selection changes and provides direct access to the CyNode and CyEdge objects.

Note: Node selection is stored in the default node table, and edge selection is stored in the default edge table, meaning that node selection and edge selection have different event sources. This results in two of these events being fired when both node and edge selection changes. It is safe to handle both events. If the listener only cares about node events this is indicated by the nodesChanged method.

Note: The event source for this event is the CyNetwork, not the default node or edge table.

Cytoscape Backwards Compatibility (SPI Interface): We expect that this interface will be implemented. Therefore to maintain backwards compatibility this interface will only be modified for major version updates.
