Constructor Details
-
Subpath
public Subpath()Creates a new SubPath instance. -
Subpath
Copy constructor. -
Subpath
Constructs a new subpath starting at the given point.- Parameters:
-
startPoint
- the point this subpath starts at
-
Subpath
public Subpath(float startPointX, float startPointY) Constructs a new subpath starting at the given point.- Parameters:
-
startPointX
- x-coordinate of the start point of subpath -
startPointY
- y-coordinate of the start point of subpath
-
-
Method Details
-
setStartPoint
Sets the start point of the subpath.- Parameters:
-
startPoint
- the point this subpath starts at
-
setStartPoint
public void setStartPoint(float x, float y) Sets the start point of the subpath.- Parameters:
-
x
- x-coordinate of the start pint -
y
- y-coordinate of the start pint
-
getStartPoint
- Returns:
- The point this subpath starts at.
-
getLastPoint
- Returns:
- The last point of the subpath.
-
addSegment
Adds a segment to the subpath. Note: each new segment shall start at the end of the previous segment.- Parameters:
-
segment
- new segment.
-
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()- Returns:
-
true
if this subpath contains only one point and it is closed,false
otherwise
-
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.
-
setClosed
public void setClosed(boolean closed) SeeisClosed()
- Parameters:
-
closed
-boolean
value indicating whether the path is closed or not.
-
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.
-
getPiecewiseLinearApproximation
- Returns:
-
List
containing points of piecewise linear approximation for this subpath.
