Interface IlvHyperEdgeEnd

All Superinterfaces:

IlvPersistentObject

All Known Implementing Classes:

IlvDefaultHyperEdgeEnd, IlvSegmentedHyperEdge.HyperEdgeEnd

public interface IlvHyperEdgeEnd
extends IlvPersistentObject

IlvHyperEdgeEnd is the end point of a hyperedge at a node. It belongs logically to the edge, not to the node. This means that different hyperedge will never share the same IlvHyperEdgeEnd object.

Since:

JViews 8.0

IlvHyperEdgeEnd	copy() Creates a copy of this object.
IlvHyperEdge	getHyperEdge() Returns the hyperedge of this end point.

IlvPoint	getPosition(IlvTransformer t, boolean checkConnector) Returns the position of the hyperedge end point in view coordinates.
void	positionChanged() Called when the position of this end might have changed.
void	setDragging(boolean dragging) Sets whether we are currently dragging the hyperedge end interactively.
void	setHyperEdge(IlvHyperEdge edge) Sets the hyperedge of this end point.
void	setPosition(IlvPoint p, IlvTransformer t) Sets the position of the hyperedge end point.
boolean	zoomable() Returns true if the end point of a hyperedge is zoomable.

Method Detail

getHyperEdge

IlvHyperEdge getHyperEdge()

Returns the hyperedge of this end point.

setHyperEdge

void setHyperEdge(IlvHyperEdge edge)

Sets the hyperedge of this end point. You should not call this method. It is automatically called after reading from IlvInputStream.

IlvPersistentObject

getNode

IlvGraphic getNode()

Returns the end node that is connected to the hyperedge by this end point.

getPosition

IlvPoint getPosition(IlvTransformer t,
                     boolean checkConnector)

Returns the position of the hyperedge end point in view coordinates.

Parameters:

t - The transformer to draw the hyperedge.

checkConnector - Whether the hyperedge connector is queried for the connection point.

setPosition

void setPosition(IlvPoint p,
                 IlvTransformer t)

Sets the position of the hyperedge end point. If the edge is inside a grapher, this must be done inside an applyToObject session of the edge (see IlvManager.applyToObject(ilog.views.IlvGraphic, ilog.views.IlvApplyObject, java.lang.Object, boolean)).

Parameters:

p - The new position of the hyperedge in view coordinates.

t - The transformer to draw the hyperedge.

setDragging

void setDragging(boolean dragging)

Sets whether we are currently dragging the hyperedge end interactively.

zoomable

boolean zoomable()

Returns true if the end point of a hyperedge is zoomable. The end point of a hyperedge is zoomable if for all transformations t the following holds:

 
 t.apply(getPosition(null, true)) == getPosition(t, true)
 

copy

IlvHyperEdgeEnd copy()

Creates a copy of this object.

positionChanged

void positionChanged()

Called when the position of this end might have changed. Reason can be that the end moved, or that the end position is relative to the node position and the node moved. This allows to clean coordinate caches.
