Method Detail

contains

public static boolean contains(org.eclipse.draw2d.geometry.Rectangle rect,
                               int x,
                               int y)

Tests whether point falls into or on bounds of rectangle.

Parameters:

rect - tested rectangle

x - X value

y - Y value

Returns:

true if falls

contains

public static boolean contains(org.eclipse.draw2d.geometry.Rectangle rect,
                               org.eclipse.draw2d.geometry.Point p)

Tests whether point falls into or on bounds of rectangle.

Parameters:

rect - tested rectangle

x - X value

y - Y value

Returns:

true if falls

computeDistance

public static double computeDistance(org.eclipse.draw2d.IFigure figure,
                                     org.eclipse.draw2d.geometry.Point p)

Computes distance of figure from point p. Distance is minimal length of any directional line between figure's bounds and point.

Parameters:

figure - to compute distance from p

p - point

Returns:

distance of figure from p

computeYDistance

public static int computeYDistance(org.eclipse.draw2d.IFigure figure,
                                   int yCoordinate)

Computes vertical distance of figure from yCoordinate horizont. Distance is minimal length of vertical line between figure's bounds and yCoordinate horizont.

Parameters:

figure - to compute distance from yCoordinate

yCoordinate - y coordinate of horizontal line

Returns:

distance of figure from yCoordinate

computeXDistance

public static int computeXDistance(org.eclipse.draw2d.IFigure figure,
                                   int xCoordinate)

Computes horizontal distance of figure from xCoordinate vertical. Distance is minimal length of horizontal line between figure's bounds and xCoordinate vertical.

Parameters:

figure - to compute distance from xCoordinate

xCoordinate - x coordinate of vertical line

Returns:

distance of figure from xCoordinate

computeDistance

public static double computeDistance(org.eclipse.draw2d.IFigure figure1,
                                     org.eclipse.draw2d.IFigure figure2,
                                     Position side)

Computes distance of sides of figures. Distance is computed as distance of lines figure's bounds on side spesified by side.

Parameters:

figure1 - argument for distance computation

figure2 - argument for distance computation

sides - of figures to compute distance, one of Position#LEFT, Position#RIGHT, Position#BOTTOM, Position#TOP

Returns:

comparePosition

public static EnumSet<Position> comparePosition(org.eclipse.draw2d.IFigure figure1,
                                                org.eclipse.draw2d.IFigure figure2)

Compares position of figure2 to figure1. If rectagles are graphically identical, then result contains Position#CONTAINS and Position#CONTAINED.

Parameters:

figure1 - to compare with

figure2 - figure to compare

Returns:

position of figure2 to figure2
