public abstract class IlvHyperEdgeConnector
extends IlvGraphic

The hyperedge connector is dedicated to the computation of the connection points of hyperedges (IlvHyperEdge) in a hypergrapher (IlvHyperGrapher).

The mechanism is slightly different than the IlvLinkConnector of IlvLinkImage. When a hyperedge is created and connected to nodes, it is attached to the point specified by IlvHyperEdgeEnd to the node. If no hyperedge connector is used, the hyper edge end can be freely moved (comparable to the IlvFreeLinkConnector of IlvLinkImage). In order to restrict the possible attachment points, a hyperedge connector can be used.

An IlvHyperEdgeConnector can be associated with a node or with a hyperedge (returned by the method getOwner()). It cannot be shared among multiple nodes and hyperedges. In order to associate the connector with a node or hyperedge, use the constructor IlvHyperEdgeConnector(IlvGraphic) or use the method attach(IlvGraphic, boolean). Notice that the same instance of hyperedge connector cannot be shared by several nodes or hyperedges.

The implementation of the method getConnectionPoint(ilog.views.hypergraph.IlvHyperEdgeEnd, ilog.views.IlvTransformer) decides where the connection point of a hyperedge end (provided as an argument) should be located. This method is called for all ends of a hyperedge if the connector is associated with the hyperedge. It is called for all ends of hyperedges ending at a node if the connector is associated with the node, except for those hyperedges that have an individual hyperedge connector.

Hyperedge connectors at nodes may be visible. For instance the pin connector IlvHyperEdgePinConnector can display the pins of the connector. Therefore, the class IlvHyperEdgeConnector is a subclass of IlvGraphic. The method isGraphic() decides whether the hyperedge connector must be displayed or whether it is purely a computation mechanism. If it is purely a computation mechanism, it is never added to any grapher.

JViews 8.0

Constructor Detail

IlvHyperEdgeConnector

public IlvHyperEdgeConnector()

Creates an empty IlvHyperEdgeConnector. To attach the connector to a node or hyperedge, call attach(ilog.views.IlvGraphic, boolean).

IlvHyperEdgeConnector

public IlvHyperEdgeConnector(IlvGraphic obj)

Creates an IlvHyperEdgeConnector attached to the input object, which can be a node or a hyperedge.

IlvHyperEdgeConnector

public IlvHyperEdgeConnector(IlvHyperEdgeConnector source)

Creates an IlvHyperEdgeConnector by copying an existing one.

Parameters:

source - The origin of the copy.

IlvHyperEdgeConnector

public IlvHyperEdgeConnector(IlvInputStream stream)
                      throws IlvReadFileException

Reads the object from an IlvInputStream.

Parameters:

stream - The input stream.

Throws:

IlvReadFileException - if the format is not correct.

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the object to an IlvOutputStream. You should not call this method directly; instead, you should use the write methods of the manager.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvGraphic

Parameters:

stream - The output stream.

Throws:

IOException - thrown when an exception occurs during the write operation for this object.

isGraphic

public boolean isGraphic()

Returns whether the connector displays a visible part. This means the connector acts like an IlvGraphic. A connector that displays a visible part can only be attached to a node, not to a hyperedge. If true, the connector is added to the same manager as the associated node, and hence is displayed in the manager. The layer where the connector is placed can be specified by the layer mode (see setLayerMode(int). This determines whether the visible part of the connector overlaps the node or not. The default implementation returns false.

attach

public void attach(IlvGraphic nodeOrEdge,
                   boolean redraw)

Installs the hyperedge connector on a node or hyperedge. After installation, the hyperedge connector controls the connection points where a hyperedge can attach at a node. If a connector is attached to a hyperedge, it controls all end points of the hyperedge. If a connector is attached to a node, it controls all end points of all incident hyperedges that are not attached to an individual connector.

The method getOwner() returns the node or hyperedge this connector is attached to.

The method detach(boolean) is automatically called to detach the old attached owner, if any. Also, if any other hyperedge connector was attached to this owner, it gets detached.

If the connector is attached to a node inside a grapher and if isGraphic() returns true, the hyperedge connector is inserted into the grapher.

Parameters:

nodeOrEdge - The node or hyperedge the connector is attached to.

redraw - If true, the manager is redrawn.

See Also:

detach(boolean)

attachImpl

protected void attachImpl(IlvGraphic obj)

This method is called inside attach(ilog.views.IlvGraphic, boolean) to attach the connector to the node or hyperedge. You should not call this. You can override this method in order to perform additional operations for specific subclasses of IlvHyperEdgeConnector.

Parameters:

obj - The node or hyperedge the connector is attached to.

detach

public void detach(boolean redraw)

Detaches the hyperedge connector from the attached node or hyperedge. Afterwards, the hyperedge connector does not anymore control the connection points where a hyperedge can attach at a node.

If the connector was attached to a node inside a grapher and if isGraphic() returns true, the hyperedge connector is removed from the grapher.

Parameters:

redraw - If true, the manager is redrawn.

See Also:

attach(IlvGraphic, boolean)

detachImpl

protected void detachImpl()

This method is called inside detach(boolean) to detach the connector from the node or hyperedge. You should not call this. You can override this method in order to perform additional operations for specific subclasses of IlvHyperEdgeConnector.

allowRemoval

public boolean allowRemoval()

Returns whether it currently allowed to remove the connector from its manager. This method exists for internal reasons.

setConnectionPointMoveAllowed

public void setConnectionPointMoveAllowed(boolean allow)

Sets whether it is globally allowed to move the connection points interactively.

See Also:

allowsConnectionPointMove(ilog.views.hypergraph.IlvHyperEdgeEnd)

isConnectionPointMoveAllowed

public boolean isConnectionPointMoveAllowed()

Returns whether it is globally allowed to move the connection points interactively.

See Also:

allowsConnectionPointMove(ilog.views.hypergraph.IlvHyperEdgeEnd)

allowsConnectionPointMove

public boolean allowsConnectionPointMove(IlvHyperEdgeEnd end)

Indicates whether the connection point of a hyperedge can be moved by interactors.

The default implementation returns the same result as isConnectionPointMoveAllowed(). Subclasses can override this method to indicate to the interactors that either all or some connection points cannot be moved.

actOnOwnerInserted

public void actOnOwnerInserted(IlvGraphic nodeOrEdge,
                               boolean redraw)

connect

public boolean connect(IlvHyperEdgeEnd end,
                       IlvPoint p,
                       IlvTransformer t)

Connect a hyperedge end to hyperedge connector. If the hyperedge is inside a grapher, this must be done inside an applyToObject session of the hyperedge that has the hyperedge end (see IlvManager.applyToObject(ilog.views.IlvGraphic, ilog.views.IlvApplyObject, java.lang.Object, boolean)).

The default implementation simply calls getClosestConnectionPoint(ilog.views.hypergraph.IlvHyperEdgeEnd, ilog.views.IlvPoint, ilog.views.IlvTransformer) and moves the hyperedge end point to this point.

Parameters:

end - The hyperedge end.

p - The proposed connection point in transformed coordinates.

t - The transformer used to draw the hyperedge.

Returns:

true if the connection was successful, false otherwise.

See Also:

disconnect(ilog.views.hypergraph.IlvHyperEdgeEnd)

disconnect

public boolean disconnect(IlvHyperEdgeEnd end)

Disconnect a hyperedge end from the hyperedge connector. This is called when the hyperedge end is removed from the hyperedge, so that the hyperedge is not anymore incident to the corresponding node. If the hyperedge is inside a grapher, this must be done inside an applyToObject session of the hyperedge that has the hyperedge end (see IlvManager.applyToObject(ilog.views.IlvGraphic, ilog.views.IlvApplyObject, java.lang.Object, boolean)). The default implementation does nothing and returns true.

Parameters:

end - The hyperedge end.

Returns:

true if the end was connected, false otherwise.

See Also:

connect(ilog.views.hypergraph.IlvHyperEdgeEnd, ilog.views.IlvPoint, ilog.views.IlvTransformer)

getConnectionPoint

public abstract IlvPoint getConnectionPoint(IlvHyperEdgeEnd end,

                                                   IlvTransformer t)

Returns the closest possible connection point of the hyperedge end at the corresponding node.

Parameters:

end - The hyperedge end.

p - The proposed point in view coordinates.

t - The transformer used to draw the hyperedge.

Returns:

The closest connection point at the node in view coordinates.

adjustAll

public void adjustAll()

Adjusts all ends connected to the hyperedge connector. This is called when the node or hyperedge has moved. The default implementation calls adjust(ilog.views.hypergraph.IlvHyperEdgeEnd) for all ends that are managed by this hyperedge connector.

adjust

public void adjust(IlvHyperEdgeEnd end)

Adjusts one ends connected to the hyperedge connector. This is called when the node or hyperedge has moved. The default implementation calls IlvHyperEdgeEnd.positionChanged().

actOnWrite

public void actOnWrite(IlvHyperEdgeEnd end,
                       IlvOutputStream stream)
                throws IOException

Called when writing the hyperedge end to the output stream. The default implementation does nothing.

You must override this method if specific data is to be stored.

You should not call this method directly; instead, you should use the write methods of the IlvGrapher that contains node or hyperedge to which the hyperedge connector is attached.

Parameters:

end - The hyperedge end.

stream - The output stream.

Throws:

IOException

actOnRead

public void actOnRead(IlvHyperEdgeEnd end,
                      IlvInputStream stream)
               throws IlvReadFileException

Called when reading the hyperedge end from the input stream. The default implementation does nothing.

You must override this method if specific data is to be read.

You should not call this method directly; instead, you should use the read methods of the IlvGrapher that contains the node or hyperedge to which the hyperedge connector is attached.

Parameters:

end - The hyperedge end.

stream - The input stream.

Throws:

IlvReadFileException

setLayerMode

public void setLayerMode(int mode)

Sets the layer mode. If the connector displays a visible part, it acts like a an IlvGraphic. In this case, isGraphic() returns true and the connector can only be attached at a node. It is added to the same manager as the associated node, and hence is displayed in the manager. The layer mode determines the manager layer where to place the connector. The options are:

• IN_NODE_LAYER - the connector is placed in the same layer as the node. This is the default.
• IN_FRONT - the connector is placed in the a layer above the node layer. The visible parts of the connector may overlap the nodes.
• IN_BACK - the connector is placed in the a layer below the node layer. The node may overlap the visible parts of the connector. This works only if the node is not in layer 0.
• IN_FIXED_LAYER - the connector is placed in a fixed layer specified by setFixedLayer(int).

See Also:

getLayerMode(), isGraphic()

getLayerMode

public int getLayerMode()

Returns the layer mode.

See Also:

setLayerMode(int)

setFixedLayer

public void setFixedLayer(int layer)

Sets the layer of the connector if the layer mode is IN_FIXED_LAYER.

See Also:

setLayerMode(int), getFixedLayer()

getFixedLayer

public int getFixedLayer()

Returns the layer of the connector if the layer mode is IN_FIXED_LAYER.

See Also:

setLayerMode(int), setFixedLayer(int)

connectionsZoomable

public boolean connectionsZoomable()

Returns true if the connection points of the hyperedge at zoomable nodes are zoomable. A connection point is zoomable if calling the method getConnectionPoint(ilog.views.hypergraph.IlvHyperEdgeEnd, ilog.views.IlvTransformer) with a transformer gives the same result as calling it with a null (identity) transformer and then applying the transformer to the result. This is only tested if the hyperedge end is attached to a zoomable node.

Note that an instance of a hyperedge connector must return the same value as long as it is attached to the same object.

The default implementation returns false.

Don't confuse this with the method zoomable() which indicates whether the connector as graphic object would be zoomable.

zoomable

public boolean zoomable()

Returns true if the object is zoomable; otherwise it returns false. This method is only used if isGraphic() returns true, i.e., if the connector behaves like an IlvGraphic.

GetAttached

public static IlvHyperEdgeConnector GetAttached(IlvGraphic nodeOrEdge)

Returns the hyperedge connector of a node or hyperedge.

Get

public static IlvHyperEdgeConnector Get(IlvHyperEdgeEnd end)

Returns the hyperedge connector that is responsible for handling the input hyperedge end. If a connector is attached to the hyperedge, this connector is returned, otherwise the connector attached to the node is returned.

Different to Get(ilog.views.hypergraph.IlvHyperEdgeEnd), this is not necessarily the connector that is currently responsible for the hyperedge end. If the hyperedge is an intergraph hyperedge and the end node is inside a collapsed grapher, then the connector of the collapsed grapher might be responsible for the hyperedge end, but instead the connector of the (currently invisible) end node is returned.
