Constructor Detail

Subpath

public Subpath()

Subpath

public Subpath(Subpath subpath)

Copy constuctor.

Parameters:

subpath -

Subpath

public Subpath(Point2D startPoint)

Constructs a new subpath starting at the given point.

Subpath

public Subpath(float startPointX,
               float startPointY)

Constructs a new subpath starting at the given point.

Method Detail

setStartPoint

public void setStartPoint(Point2D startPoint)

Sets the start point of the subpath.

Parameters:

startPoint -

setStartPoint

public void setStartPoint(float x,
                          float y)

Sets the start point of the subpath.

Parameters:

x -

y -

getStartPoint

public Point2D getStartPoint()

Returns:

The point this subpath starts at.

getLastPoint

public Point2D getLastPoint()

Returns:

The last point of the subpath.

addSegment

public void addSegment(Shape segment)

Adds a segment to the subpath. Note: each new segment shall start at the end of the previous segment.

Parameters:

segment - new segment.

getSegments

public List<Shape> getSegments()

Returns:

List comprising all the segments the subpath made on.

isEmpty

public boolean isEmpty()

Checks whether subpath is empty or not.

Returns:

true if the subpath is empty, false otherwise.

isSinglePointOpen

public boolean isSinglePointOpen()

Returns:

true if this subpath contains only one point and it is not closed, false otherwise

isSinglePointClosed

public boolean isSinglePointClosed()

isClosed

public boolean isClosed()

Returns a boolean value indicating whether the subpath must be closed or not. Ignore this value if the subpath is a rectangle because in this case it is already closed (of course if you paint the path using re operator)

Returns:

boolean value indicating whether the path must be closed or not.

Since:

5.5.6

setClosed

public void setClosed(boolean closed)

See isClosed()

isDegenerate

public boolean isDegenerate()

Returns a boolean indicating whether the subpath is degenerate or not. A degenerate subpath is the subpath consisting of a single-point closed path or of two or more points at the same coordinates.

Returns:

boolean value indicating whether the path is degenerate or not.

Since:

5.5.6

getPiecewiseLinearApproximation

public List<Point2D> getPiecewiseLinearApproximation()

Returns:

List containing points of piecewise linear approximation for this subpath.

Since:
