Default renderer implementation for BridgeEdgeStyle.
Type Details
- yfiles module
- styles-other
- yfiles-umd modules
- All view modules
- Legacy UMD name
- yfiles.styles.BridgeEdgeStyleRenderer
Properties
Gets whether the rendered path should use the BridgeManager to add bridges to it.
Gets or sets the currently configured edge.
Defined in
Gets or sets the distance between the node's layout and its self loop control points.
Defined in
Gets or sets the policy with which smoothing is applied to the path when getSmoothingLength returns a value larger than 0.
Gets or sets a value indicating whether the first and last segments of the path should always begin and end with a straight line segment, respectively.
Remarks
Given high enough values for getSmoothingLength, the first and last segments may become completely curved. This property prevents this from happening, e.g. to prevent arrowheads from colliding with the smoothed edge path.
The default value is false.
Defined in
Gets or sets the currently configured style.
Defined in
Methods
Prepares this instance for subsequent calls after the style and edge have been initialized.
Remarks
Upon invocation the style and edge properties have been populated by the getVisualCreator, getBoundsProvider, getHitTestable, or getMarqueeTestable methods.
Subclasses which override this method have to call the base implementation, first.
Overrides
This method should create the basic uncropped path given the control points.

A map of options to pass to the method.

This method is overridden for performance reasons.
Remarks
This implementation uses isVisible as an early exit indicator. If isVisible returns false for a certain rectangle, the instance will not be configured but a non-hit will be assumed. Otherwise this instance will be configured and the standard path based hit test routine
Subclasses should not depend on the fact that configure has already been called. This may not be the case. If your subclass depends on Configure being called, override getHitTestable and call configure after the base class call.

Overrides
Returns an instance that implements the given type or null.
Remarks
null implementations for the types, nor does it have to return the same instance any time. Also it depends on the type and context whether the instance returned stays up to date or needs to be reobtained for subsequent use.Type Parameters
- T: any
Parameters
A map of options to pass to the method.

- The type for which an instance shall be returned.

Overrides
This method updates or replaces a previously created Visual for inclusion in the IRenderContext.
Remarks
The CanvasComponent uses this method to give implementations a chance to update an existing Visual that has previously been created by the same instance during a call to createVisual. Implementation may update the oldVisual and return that same reference, or create a new visual and return the new instance or null.
I most cases oldVisual is a visual instance that has been returned by the createVisual method of this instance. This is, however, not guaranteed. Implementations have to be aware of this.
Parameters
A map of options to pass to the method.
- context - IRenderContext
- The context that describes where the visual will be used in.
- oldVisual - Visual
- The visual instance to be updated.
Returns
- ↪Visual
oldVisual, if this instance modified the visual, or a new visual that should replace the existing one in the canvas object visual tree.
