Method Detail

getPointCount

int getPointCount()

Returns the number of points in the sequence.

Returns:

number of points in the sequence

getX

double getX(int i)

Returns the x component of the point at the given index.

Parameters:

i - index of desired point

Returns:

x component of point

getY

double getY(int i)

Returns the y component of the point at the given index.

Parameters:

i - index of desired point

Returns:

y component of point

getPoint

Point2D getPoint(int i,
                 Point2D dst)

Returns a point representation of the coordinates at the given index.

Parameters:

i - index of desired point

dst - output parameter into which the point's details will be populated, if null a new one will be created.

Returns:

a point representation of the coordinates at the given index

getBounds

Rectangle2D getBounds(Rectangle2D dst)

Returns the bounds of all the points taken as a whole.

Parameters:

dst - output parameter to store bounds into, if null a new rectangle will be created

Returns:

rectangle containing the bounds
