An empty block with a fixed size.

Constructor:

Constructor:
public EmptyBlock(double width, double height) { setWidth(width); setHeight(height); } Creates a new block with the specified width and height. Parameters: `width` - the width. `height` - the height.

Method from org.jfree.chart.block.EmptyBlock Detail:
public Size2D arrange(Graphics2D g2, RectangleConstraint constraint) { Size2D base = new Size2D(calculateTotalWidth(getWidth()), calculateTotalHeight(getHeight())); return constraint.calculateConstrainedSize(base); } Arranges the contents of the block, within the given constraints, and returns the block size.
public Object clone() throws CloneNotSupportedException { return super.clone(); } Returns a clone of the block.
public void draw(Graphics2D g2, Rectangle2D area) { draw(g2, area, null); } Draws the block. Since the block is empty, there is nothing to draw except the optional border.
public Object draw(Graphics2D g2, Rectangle2D area, Object params) { area = trimMargin(area); drawBorder(g2, area); return null; } Draws the block within the specified area. Since the block is empty, there is nothing to draw except the optional border.

Method from org.jfree.chart.block.EmptyBlock Detail:

 public Size2D arrange(Graphics2D g2,
    RectangleConstraint constraint) {
        Size2D base = new Size2D(calculateTotalWidth(getWidth()),
                calculateTotalHeight(getHeight()));
        return constraint.calculateConstrainedSize(base);
}

Arranges the contents of the block, within the given constraints, and returns the block size.

 public Object clone() throws CloneNotSupportedException {
        return super.clone();
}

Returns a clone of the block.

 public  void draw(Graphics2D g2,
    Rectangle2D area) {
        draw(g2, area, null);
}

Draws the block. Since the block is empty, there is nothing to draw except the optional border.

 public Object draw(Graphics2D g2,
    Rectangle2D area,
    Object params) {
        area = trimMargin(area);
        drawBorder(g2, area);
        return null;
}

Draws the block within the specified area. Since the block is empty, there is nothing to draw except the optional border.
