CurvedLinkRenderer

public CurvedLinkRenderer(GraphicsBase<?> graphics,
String name)

Constructs a new link renderer.

Method Details

drawStartToStart

protected void drawStartToStart(GraphicsContext gc,
Rectangle2D sourceRect,
Rectangle2D targetRect)

Draws a link in the given graphics context from the start of the source rectangle to the start of the target rectangle.

Specified by:

drawStartToStart in class LinkRenderer<T extends ActivityLink<?>>

Parameters:

sourceRect - the source rectangle

targetRect - the target rectangle

drawEndToEnd

protected void drawEndToEnd(GraphicsContext gc,
Rectangle2D sourceRect,
Rectangle2D targetRect)

Draws a link in the given graphics context from the end of the source rectangle to the end of the target rectangle.

Specified by:

drawEndToEnd in class LinkRenderer<T extends ActivityLink<?>>

Parameters:

sourceRect - the source rectangle

targetRect - the target rectangle

drawStartToEnd

protected void drawStartToEnd(GraphicsContext gc,
Rectangle2D sourceRect,
Rectangle2D targetRect)

Draws a path in the given graphics context from the start of the source rectangle to the end of the target rectangle.

Specified by:

drawStartToEnd in class LinkRenderer<T extends ActivityLink<?>>

Parameters:

sourceRect - the source rectangle

targetRect - the target rectangle

drawEndToStart

protected void drawEndToStart(GraphicsContext gc,
Rectangle2D sourceRect,
Rectangle2D targetRect)

Draws a path in the given graphics context from the end of the source rectangle to the start of the target rectangle.

Specified by:

drawEndToStart in class LinkRenderer<T extends ActivityLink<?>>

Parameters:

sourceRect - the source rectangle

targetRect - the target rectangle

setCurve

public final void setCurve(double curve)

Sets the radius for the curve. The radius can not be larger than the offset (see LinkRenderer.setOffset(double)). Setting this value to 0 results in corners instead of curves (but then you might consider using the StraightLinkRenderer as it is more efficient).

Parameters:

curve - the radius of the curve

getCurve

public final double getCurve()

Returns the radius of the curve.

Returns:

the curve radius
