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 java.util.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 aboolean
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 usingre
operator)- Returns:
boolean
value indicating whether the path must be closed or not.- Since:
- 5.5.6
-
setClosed
public void setClosed(boolean closed)
SeeisClosed()
-
isDegenerate
public boolean isDegenerate()
Returns aboolean
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 java.util.List<Point2D> getPiecewiseLinearApproximation()
- Returns:
List
containing points of piecewise linear approximation for this subpath.- Since:
- 5.5.6
