The inner height of this DiagramLink.

The inner left position (X coordinate).

The inner top position (Y coordinate).

The inner width of this DiagramLink.

Indicates whether the parent of the layer containing this DiagramLink is a DiagramLane.

The DiagramLayer that contains this DiagramLink.

Used line color for drawing this DiagramLink.

Color for the normal link behaviour

Color for the link in feedback mode

Used line opacity for drawing this DiagramLink.

Used line width for drawing this DiagramLink.

Behaviour, geometry, css style

Size of a control point graphical marker.

Indicates whether the parent of the layer containing this DiagramLink is a DiagramPanel.

An array containing this list of the control points of this DiagramLink.

The AnchorPoint that attaches this DiagramLink to its master DiagramObject.

The master DiagramObject of this DiagramLink.

CSS style selector (defined in the library)

Name of the style selector to be used to render this DiagramLink.

Target anchor point linking to a target DiagramObject.

The AnchorPoint that attaches this DiagramLink to its target DiagramObject.

ID of the Target AnchorPoint.

The target DiagramObject of this DiagramLink.

Indicates whether the parent of the layer containing this DiagramLink is the DiagramPanelsContainer of the current DiagramView.

Extended graphics wrapper

Creates a new DiagramLink instance.

Adds this DiagramLink object in SVG format to an SVGSVGElement object.

Applies the transformation matrix matrix to this DiagramLink component.

Determines the rectangle that contains this DiagramLink.

Updates the position of the DiagramLink after the dragging action is finished.

Draws this DiagramLink elements (control points as circles, H/V lines connecting control points, link arrow, source and target markers...) while respecting control points and style properties.

Parses this DiagramLink from an XML object.

Returns intersection point (if any) of diagramlink with given rectangle

Returns an object containing clipping information about a polyline object defined by its control points clipping with a Sprite object sprite considered as a source object of a DiagramLink polyline. This method is used to enable drawing a DiagramLink polyline from a source Sprite

Returns This DiagramLink tagname equal to "link".

Returns an object containing clipping information about a polyline object defined by its control points clipping with a Sprite object sprite considered as a target object of a DiagramLink polyline. This method is used to enable drawing a DiagramLink polyline from a source Sprite

Hides feedback effect on link

Initialises this DiagramLink instance with the required link parameters.

Checks if orthogonal diagramLink intersects with rectangle

Marks the DiagramLink component so that its updateDisplayList() method gets called during a later screen update to render the new library styles.

Changes the position of this DiagramLink component according to changes on the Target or Master AnchorPoint. This anchor point must be the source or target AnchorPoint of this DiagramLink in order to inflict updates on this DiagramLink component.

Removes this DiagramLink from its parent container after that its Master DiagramObject has been removed and updates master or target Anchor point.

Called after this DiagramLink has been added to its parent layer

Adds a third point to the points array if it contains only two points. In this case the coordinates of the third point are equal to the coordinates of the second point. It is essential that any link has at least three points so that the object it links can be moved freely horizontaly and vertically.

Shows feedback effect on link

Transforms the points array into an array of three points by keeping only the first and last points and adding a third one in the middle.

Marks the DiagramLink component so that its updateDisplayList() method gets called during a later screen update to render the new system library styles.

Writes this DiagramLink into an XML object.

Finalizes modifications on this DiagramLink, transmitted by its DiagramLinkUI. This method is called when user interaction with the correspondant DiagramLinkUI is completed and resulting DiagramLink update must be applied.

Removes all link references (master and target anchor points) of this DiagramLink.

Updates Column Scope.

Draws the DiagramLink and/or sizes and positions its children. This method is called when the component is added to a container using the addChild() method, and when the component's invalidateDisplayList() method is called.

Changes the position of this DiagramLink component according to changes on the Target or Master AnchorPoint. This anchor point must be the source or target AnchorPoint of this DiagramLink in order to inflict updates on this DiagramLink component.

Detects changes in dependancy toward the container of this DiagramLink, due to user modificatiosn on the source and target DiagramObject components, and updates it. In fact, in cases where this DiagramLink is modified to link DiagramObject components embedded in different lanes of a panel (or mbedded in different panels of a panels container), this DiagramLink must be removed from its current container and placed in the LinksLayer of that panel (panels container). This is what we call change in the scope of this DiagramLink. When called, this method updates the scope of this DiagramLink using knowledge about source and target DiagramObjects (source.master and target.master).

Updates style properties of this DiagramLink.

Modifies the UI class (a DiagramLinkUI subclass) according to this DiagramLink's behaviour

Inflicts changes in the source layer and target layer on the container (DiagramLane or DiagramPanel) of the DiagramLinkUI _ui controlling this DiagramLink.
