hasBlock

public abstract boolean hasBlock()

getBlockWidth

public abstract double getBlockWidth()

getBlockTopHeight

public abstract double getBlockTopHeight()

getBlockBottomHeight

public abstract double getBlockBottomHeight()

drawBackEdgeArrowHead

protected void drawBackEdgeArrowHead(java.awt.Graphics2D g2,
                                     double x,
                                     double y,
                                     boolean downwards)

drawRoundedPolyline

protected void drawRoundedPolyline(java.awt.Graphics2D g2,
                                   double arc,
                                   java.awt.geom.Point2D... coordinates)

Draws an orthogonal polyline with rounded corners. The polyline needs to be orthogonal, that is, every segment should be horizontal or vertical. Furthermore horizontal and vertical segments should alternate.

Parameters:

g2 - The Graphics2D object to use.

arc - The arc radius.

coordinates - A list of coordinates to draw.

Throws:

java.lang.IllegalArgumentException - If the polyline is not orthogonal.

removeEmptySegments
