Method Summary

protected static double	centerX(PNode node, double x, double width) Returns the x at which the given node would need to be placed so that its center was in the middle of the horizontal segment defined by x and width.
protected static double	centerY(PNode node, double y, double height) Returns the y at which the given node would need to be placed so that its center was in the middle of the vertical segment defined by y and h.
protected static double	east(PNode node, double x, double width) Returns the x at which the given node would need to be placed so that its right side was against the right side of the horizontal range defined.
protected static double	north(PNode node, double y, double height) Returns the y at which the given node would need to be placed so that its top was against the top of the vertical segment defined.
protected static double	south(PNode node, double y, double height) Returns the y at which the given node would need to be placed so that its bottom was against the bottom of the vertical range defined.
protected static double	west(PNode node, double x, double width) Returns the x at which the given node would need to be placed so that its left side was against the left side of the horizontal range defined.

Method Detail

centerX

protected static double centerX(PNode node,
                                double x,
                                double width)

Returns the x at which the given node would need to be placed so that its center was in the middle of the horizontal segment defined by x and width.

Parameters:

node - node which is being analyzed

x - x component of horizontal line segment

width - width of horizontal line segment

Returns:

x at which node would need to be placed so that its center matched the center of the line segment

centerY

protected static double centerY(PNode node,
                                double y,
                                double height)

Returns the y at which the given node would need to be placed so that its center was in the middle of the vertical segment defined by y and h.

Parameters:

node - node which is being analyzed

y - y component of horizontal line segment

height - height of vertical line segment

Returns:

y at which node would need to be placed so that its center matched the center of the line segment

north

protected static double north(PNode node,
                              double y,
                              double height)

Parameters:

node - node which is being analyzed

y - y component of horizontal line segment

height - height of vertical line segment

Returns:

y at which node would need to be placed so that its top matched the start of the line segment (y)

south

protected static double south(PNode node,
                              double y,
                              double height)
