All Superinterfaces:

CyIdentifiable

public interface CyEdge
extends CyIdentifiable

An object that represents an edge within a network of nodes (vertices) and edges.

Cytoscape Backwards Compatibility (API Interface): We expect that this interface will be used but not implemented by developers using this interface. As such, we reserve the right to add methods to the interface as part of minor version upgrades. We will not remove methods for any changes other than major version upgrades.

Method Detail

getSource

CyNode getSource()

Returns the source node determining this edge. It will never be null. For undirected networks this method will consistently return the same node.

Returns:

The source node of this edge.

getTarget

CyNode getTarget()

Returns the target node determining this edge. It will never be null. For undirected networks this method will consistently return the same node.

Returns:

The target node of this edge.

isDirected

boolean isDirected()

This will return true if the edge is directed and false if the node is undirected.

Returns:

Returns true if this edge is directed and false if the node is undirected.
