public final class GeneralPath extends Path2D.Float
TheGeneralPath
class represents a geometric path constructed from straight lines, and quadratic and cubic (Bézier) curves. It can contain multiple subpaths.GeneralPath
is a legacy final class which exactly implements the behavior of its superclassPath2D.Float
. Together withPath2D.Double
, thePath2D
classes provide full implementations of a general geometric path that support all of the functionality of theShape
andPathIterator
interfaces with the ability to explicitly select different levels of internal coordinate precision.Use
Path2D.Float
(or this legacyGeneralPath
subclass) when dealing with data that can be represented and used with floating point precision. UsePath2D.Double
for data that requires the accuracy or range of double precision.- Since:

GeneralPath
public GeneralPath()
Constructs a new empty single precisionGeneralPath
object with a default winding rule ofPath2D.WIND_NON_ZERO
.- Since:
- 1.2
-
GeneralPath
public GeneralPath(int rule)
Constructs a newGeneralPath
object with the specified winding rule to control operations that require the interior of the path to be defined.- Parameters:
rule
- the winding rule- Since:
- 1.2
- See Also:
Path2D.WIND_EVEN_ODD
,Path2D.WIND_NON_ZERO
-
GeneralPath
public GeneralPath(int rule, int initialCapacity)
Constructs a newGeneralPath
object with the specified winding rule and the specified initial capacity to store path coordinates. This number is an initial guess as to how many path segments will be added to the path, but the storage is expanded as needed to store whatever path segments are added.- Parameters:
rule
- the winding ruleinitialCapacity
- the estimate for the number of path segments in the path- Since:
- 1.2
