drawNode

java.awt.Shape drawNode(Node node,
                        Position position,
                        java.awt.Graphics graphics,
                        java.awt.Color background,
                        Shape shape)

Draw the given node at the given position, with the given Graphics object.

Parameters:

node - The node to draw.

position - The screen position at which to draw the node.

graphics - The Graphics object to draw the node with.

background - The background color to draw the node with.

shape - The shape to draw the node as.

Returns:

The shape which the node occupies on screen.

drawEdge

void drawEdge(Edge edge,
              java.util.List<Position> intermediatePosition,
              java.awt.Graphics graphics)

Draw the given edge through the given intermediate positions, with the given Graphics object.

Parameters:

edge - The edge to draw.

intermediatePosition - The positions to draw the edge through. The edge should be drawn in segments of intermediatePositions[0] -> intermediatePositions[1] -> intermediatePositions[2] ...

graphics - The Graphics object to draw the edge with.

horizontalBorder

default double horizontalBorder()

The horizontal border needed by the drawn nodes.

verticalBorder

default double verticalBorder()

The vertical border needed by the drawn nodes.
