Class fi.helsinki.cs.MapDrawer.RelPoint 

java.lang.Object
   |
   +----fi.helsinki.cs.MapDrawer.RelPoint
public class RelPoint
extends Object
implements Serializable
MapDrawer's relative point class - This class is needed because MapDrawer doesn't use integer coordinates. For MapDrawer, the coordinates should be in the range ( [-1, 1], [-1, 1] ), but the class can be used more generally, too.

Variable Index

o x
The x coordinate of the point.
o y
The y coordinate of the point.

Constructor Index

o RelPoint()
Sets both coordinates to zero.
o RelPoint(double, double)
o RelPoint(RelPoint)

Method Index

o bound(RelRect)
Checks if the point is within a specified rectangle.
o equals(RelPoint)
o in(RelRect)
Checks whether this RelPoint is within the given RelRect.
o toPoint(Rectangle)
Translate this RelPoint to Point.
o toString()
o xScale(double)
Scales the point so that its polar coord.
o yScale(double)
Scales the point so that its polar coord.

Variables

o x 
 public double x
The x coordinate of the point.

o y 
 public double y
The y coordinate of the point.

Constructors

o RelPoint 
 public RelPoint()
Sets both coordinates to zero.

o RelPoint 
 public RelPoint(RelPoint src)
o RelPoint 
 public RelPoint(double ix,
                 double iy)

Methods

o in 
 public boolean in(RelRect b)
Checks whether this RelPoint is within the given RelRect.

o equals 
 public boolean equals(RelPoint cmp)
o toString 
 public String toString()
Overrides:
toString in class Object
o xScale 
 public void xScale(double nx)
Scales the point so that its polar coord. angle remains the same.

Parameters:
nx - the new x coordinate.
o yScale 
 public void yScale(double ny)
Scales the point so that its polar coord. angle remains the same.

Parameters:
ny - the new y coordinate.
o bound 
 public void bound(RelRect b)
Checks if the point is within a specified rectangle. If not, the point is scaled appropriately.

Parameters:
b - The bounding rectangle. NB: the results of this method are unreliable if b doesn't include the origo.
o toPoint 
 public Point toPoint(Rectangle scale)
Translate this RelPoint to Point.

Parameters:
scale - the rectangle the coord. plane of which this RelPoint is translated to.
