Constructor Detail

AbstractPointListShape

public AbstractPointListShape()
Method Detail

containsPoint

public boolean containsPoint(int x,
                             int y)
Description copied from interface: IFigure
Returns true if the point (x, y) is contained within this IFigure's bounds.

Specified by:
containsPoint in interface IFigure
Overrides:
containsPoint in class Figure
See Also:
IFigure.containsPoint(int, int)

childrenContainsPoint

protected boolean childrenContainsPoint(int x,
                                        int y)
Returns true if the point (x, y) is contained within one of the child figures.

Parameters:
x - The X coordinate
y - The Y coordinate
Returns:
true if the point (x,y) is contained in one of the child figures

shapeContainsPoint

protected abstract boolean shapeContainsPoint(int x,
                                              int y)
Returns true if the point (x, y) is contained within this figure.

Parameters:
x - The X coordinate
y - The Y coordinate
Returns:
true if the point (x,y) is contained in this figure

addPoint

public void addPoint(
Point pt)
Adds the passed point to this figure.

Parameters:
pt - the Point to be added to this figure

getStart

public 
Point getStart()
Returns:
the first point in this figure

getEnd

public 
Point getEnd()
Returns the last point in this Figure.

Returns:
the last point

getPoints

public 
PointList getPoints()
Returns the points in this figure by reference. If the returned list is modified, this figure must be informed by calling setPoints(PointList). Failure to do so will result in layout and paint problems.

Returns:
this Polyline's points

insertPoint

public void insertPoint(
Point pt,
                        int index)
Inserts a given point at a specified index in this figure.

Parameters:
pt - the point to be added
index - the position in this figure where the point is to be added

removeAllPoints

public void removeAllPoints()
Erases this figure and removes all of its Points.


removePoint

public void removePoint(int index)
Removes a point from this figure.

Parameters:
index - the position of the point to be removed

setStart

public void setStart(
Point start)
Sets the start point of this figure

Parameters:
start - the point that will become the first point in this figure

setEnd

public void setEnd(
Point end)
Sets the end point of this figure

Parameters:
end - the point that will become the last point in this figure

setEndpoints

public void setEndpoints(
Point start,
                         
Point end)
Sets the points at both extremes of this figure

Parameters:
start - the point to become the first point in this figure
end - the point to become the last point in this figure

setPoint

public void setPoint(
Point pt,
                     int index)
Sets the point at index to the Point pt. If you're going to set multiple Points, use setPoints(PointList).

Parameters:
pt - the point
index - the index

setPoints

public void setPoints(
PointList points)
Sets the list of points to be used by this figure. Removes any previously existing points. This figure will hold onto the given list by reference.

Parameters:
points - new set of points
