Method Summary

Point2D	calculateHandleLocation(CyNetworkView netView, View<CyEdge> edgeView) Calculate absolute position of this handle for the given edge view.

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.
