Constructor Detail

IlvPoint

public IlvPoint()

Creates a new IlvPoint with coordinates (0, 0).

IlvPoint

public IlvPoint(double x,
                double y)

Creates a new IlvPoint with the specified coordinates.

Parameters:

x - the x coordinate.

y - the y coordinate.

IlvPoint

public IlvPoint(IlvPoint p)

Creates a new IlvPoint by copying the specified point.

Parameters:

p - The point to copy.

Method Detail

translate

public final void translate(double dx,
                            double dy)

Translates the point.

move

public final void move(double x,
                       double y)

Changes the point location.

floor

public final void floor()

Modifies the point so that the coordinates becomes mathematical integers. This is useful when you need to use a point to draw on a view.

See Also:

xFloor(), yFloor(), IlvTransformer.applyFloor(ilog.views.IlvPoint)

xFloor

public final int xFloor()

Returns the x coordinate of the point as a mathematical integer. This is useful when you need to use a point to draw on a view.

See Also:

floor(), yFloor(), IlvTransformer.applyFloor(ilog.views.IlvPoint)

yFloor

public final int yFloor()

Returns the y coordinate of the point as a mathematical integer. This is useful when you need to use a point to draw on a view.

floor(), xFloor(), IlvTransformer.applyFloor(ilog.views.IlvPoint)

toString

public String toString()

Returns a String that represents the value of this IlvPoint.

Overrides:

toString in class Point2D.Double

Returns:

a string representation of this IlvPoint.

equalsOrNear

public boolean equalsOrNear(IlvPoint otherPoint)

Test equality of 2 IlvPoint according default precision
