Method Detail

setPoint

void setPoint(int i,
              double x,
              double y)

Sets the coordinates for the point at the given index.

Parameters:

i - index of point

x - x component of the point's coordinates

y - y component of the point's coordinates

addPoint

void addPoint(int pos,
              double x,
              double y)

Inserts a point at the specified position.

Parameters:

pos - position at which to insert the point

x - x component of the point's coordinates

y - y component of the point's coordinates

removePoints

void removePoints(int pos,
                  int num)

Removes a subsequence of points.

Parameters:

pos - position to start removing points

num - number of points to remove

transformPoints

void transformPoints(AffineTransform t)

Modifies all points by applying the transform to them.

Parameters:

t - transformto apply to the points
