public class FigTransition

extends FigEdgeModelElement

This class represents the graphical representation of a transition on a diagram.

Serialized Form

FigTransition

public FigTransition()

The main constructor.

FigTransition

public FigTransition(Object edge,
                     Layer lay)

The constructor that hooks the Fig into an existing UML element. It also adapts the line to be dashed if the source or destination is an ObjectFlowState.

Parameters:

edge - the UML element

lay - the layer

setOwner

public void setOwner(Object newOwner)

Description copied from class: FigEdgeModelElement

This method should only be called once for any one Fig instance that represents a model element (ie not for a FigEdgeNote). It is called either by the constructor that takes an model element as an argument or it is called by PGMLStackParser after it has created the Fig by use of the empty constructor. The assigned model element (owner) must not change during the lifetime of the Fig. TODO: It is planned to refactor so that there is only one Fig constructor. When this is achieved this method can refactored out.

Overrides:

setOwner in class FigEdgeModelElement

See Also:

FigEdgeModelElement.setOwner(java.lang.Object)

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:

FigEdgeModelElement.initNotationProviders(java.lang.Object)

setFig

public void setFig(Fig f)

See Also:

FigEdge.setFig(org.tigris.gef.presentation.Fig)

textEdited

protected void textEdited(FigText ft)

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)

modelChanged

protected void modelChanged(PropertyChangeEvent e)

This is called after any part of the UML ModelElement has changed. This method automatically updates the attached FigText.

Overrides:

modelChanged in class FigEdgeModelElement

Parameters:

e - the event

See Also:

FigEdgeModelElement.modelChanged(java.beans.PropertyChangeEvent)

getDestination

protected Object getDestination()

Description copied from class: FigEdgeModelElement

Returns the destination of the edge. The destination is the owner of the node the edge travels to in a binary relationship. For instance: for a classifierrole, this is the receiver.

Overrides:

getDestination in class FigEdgeModelElement

Returns:

a model element

See Also:

FigEdgeModelElement.getDestination()

getSource

protected Object getSource()

Description copied from class: FigEdgeModelElement

Returns the source of the edge. The source is the owner of the node the edge travels from in a binary relationship. For instance: for a classifierrole, this is the sender.

Overrides:

getSource in class FigEdgeModelElement

Returns:

a model element

See Also:

FigEdgeModelElement.getSource()

paint

public void paint(Graphics g)

See Also:

Fig.paint(java.awt.Graphics)

updateNameText

protected void updateNameText()

Updates the name text box. In case of a transition the name text box contains:

• The event-signature
• The guard condition between []
• The action expression

The contents of the text box is generated by the notationProvider

Overrides:

updateNameText in class FigEdgeModelElement

See Also:

FigEdgeModelElement.updateNameText()

paintClarifiers

public void paintClarifiers(Graphics g)

Overrides:

paintClarifiers in class FigEdgeModelElement

Parameters:

g - the Graphics object

FigEdgeModelElement.paintClarifiers(java.awt.Graphics)
