Interface Handle

public interface Handle

Defines a handle, an anchor point in the edge.

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 Summary

Point2D	calculateHandleLocation(CyNetworkView netView, View<CyEdge> edgeView) Calculate absolute position of this handle for the given edge view.
void	defineHandle(CyNetworkView netView, View<CyEdge> edgeView, double x, double y) Define this handle.
String	getSerializableString() Create string representation of this object for parsing.

Method Detail

calculateHandleLocation

Point2D calculateHandleLocation(CyNetworkView netView,
                                View<CyEdge> edgeView)

Calculate absolute position of this handle for the given edge view.

Parameters:

netView - graph view for this handle

edgeView - The handle belongs to this edge view.

Returns:

Absolute position of this handle in the network view.

defineHandle

void defineHandle(CyNetworkView netView,
                  View<CyEdge> edgeView,
                  double x,
                  double y)

Define this handle. Handle will be described as a relative location from source and target node. NOTE: in the implementation, the given (x, y) values will be converted to relative position. The conversion equation is exchangeable.

Parameters:

netView - graph view for this handle

edgeView - The handle belongs to this edge view.

x - Absolute value for X-location.

y - Absolute value for Y-location.

getSerializableString

String getSerializableString()

Create string representation of this object for parsing.

Returns:

String representation of this Handle.
