Direct Known Subclasses:

FigAssociationClass, FigAssociationRole

public class FigAssociation

extends FigEdgeModelElement

This class represents the Fig of a binary association on a diagram.

notationProviderSrcRole

protected NotationProvider4 notationProviderSrcRole

notationProviderDestRole

protected NotationProvider4 notationProviderDestRole

FigAssociation

public FigAssociation()

Main constructor Don't call this constructor directly. It is public since this is necessary for loading. Use the FigAssociation(Object, Layer) constructor instead!

FigAssociation

public FigAssociation(Object edge,
                      Layer lay)

Constructor that hooks the Fig to an existing UML element.

Parameters:

edge - the UMl element

lay - the layer

initNotationProviders

protected void initNotationProviders(Object own)

Description copied from class: FigEdgeModelElement

Create the NotationProviders.

Overrides:

initNotationProviders in class FigEdgeModelElement

Parameters:

own - the current owner

See Also:

FigNodeModelElement.initNotationProviders(java.lang.Object)

updateListeners

public void updateListeners(Object oldOwner,
                            Object newOwner)

Description copied from class: FigEdgeModelElement

Implementations of this method should register/unregister the fig for all (model)events. For FigEdgeModelElement only the fig itself is registered as listening to events fired by the owner itself. But for, for example, FigAssociation the fig must also register for events fired by the stereotypes of the owner.

This function is used in UMLDiagram, which removes all listeners to all Figs when a diagram is not displayed, and restore them when it becomes visible again.

In this case, it is not imperative that indeed ALL listeners are updated, as long as the ones removed get added again and vice versa.

Additionally, this function may be used by the modelChanged() function.

In this case, it IS imperative that all listeners get removed / added.

Overrides:

updateListeners in class FigEdgeModelElement

Parameters:

newOwner - the new owner for the listeners

See Also:

org.argouml.uml.diagram.ui.FigEdgeModelElement#updateListeners(java.lang.Object)

textEdited

protected void textEdited(FigText ft)

Description copied from class: FigEdgeModelElement

This method is called after the user finishes editing a text field that is in the FigEdgeModelElement. Determine which field and update the model. This class handles the name, subclasses should override to handle other text elements.

Overrides:

textEdited in class FigEdgeModelElement

Parameters:

ft - the text Fig that has been edited

See Also:

FigEdgeModelElement.textEdited(org.tigris.gef.presentation.FigText)

textEditStarted

protected void textEditStarted(FigText ft)

Description copied from class: FigEdgeModelElement

This method is called when the user doubleclicked on the text field, and starts editing. Subclasses should overrule this field to e.g. supply help to the user about the used format.

It is also possible to alter the text to be edited already here, e.g. by adding the stereotype in front of the name, but that seems not user-friendly.

Overrides:

textEditStarted in class FigEdgeModelElement

Parameters:

ft - the FigText that will be edited and contains the start-text

See Also:

FigEdgeModelElement.textEditStarted(org.tigris.gef.presentation.FigText)

propertyChange

public void propertyChange(PropertyChangeEvent e)

Specified by:

propertyChange in interface PropertyChangeListener

Overrides:

propertyChange in class FigEdgeModelElement

See Also:

PropertyChangeListener.propertyChange(java.beans.PropertyChangeEvent)

modelChanged

protected void modelChanged(PropertyChangeEvent e)

Description copied from class: FigEdgeModelElement

This is called after any part of the UML ModelElement has changed. This method automatically updates the name FigText. Subclasses should override and update other parts.

Overrides:

modelChanged in class FigEdgeModelElement

Parameters:

e - the event

See Also:

FigEdgeModelElement.modelChanged(java.beans.PropertyChangeEvent)

renderingChanged

protected void renderingChanged()

Description copied from class: FigEdgeModelElement

Rerenders the fig if needed. This functionality was originally the functionality of modelChanged but modelChanged takes the event now into account.

NOTE: If you override this method you probably also want to override the modelChanged() method TODO: Call this method something sensible. What it does rather than one example of when it is called. Its purpose seems to be to update everything if anything has changed. Not very efficient.

Overrides:

renderingChanged in class FigEdgeModelElement

See Also:

FigEdgeModelElement.renderingChanged()

getPopUpActions

public Vector getPopUpActions(MouseEvent me)

Specified by:

getPopUpActions in interface PopupGenerator

Overrides:

getPopUpActions in class FigEdgeModelElement

See Also:

PopupGenerator.getPopUpActions(java.awt.event.MouseEvent)

updateAbstract

protected void updateAbstract()

Updates the name if modelchanged receives an "isAbstract" event.

paint

public void paint(Graphics g)

See Also:

Fig.paint(java.awt.Graphics)

paintClarifiers

public void paintClarifiers(Graphics g)

Overrides:

paintClarifiers in class FigEdgeModelElement

Parameters:

g - the Graphics object

See Also:

FigEdgeModelElement.paintClarifiers(java.awt.Graphics)

getMiddleGroup

protected FigTextGroup getMiddleGroup()

Returns:

Returns the middleGroup.

layoutEdge

protected void layoutEdge()

Lays out the association edges as any other edge except for special rules for an association that loops back to the same class. For this it is snapped back to the bottom right corner if it resized to the point of not being visible.

FigEdgePoly.layoutEdge()
