public final class GeneralPath extends Path2D.Float
TheGeneralPathclass represents a geometric path constructed from straight lines, and quadratic and cubic (Bézier) curves. It can contain multiple subpaths.GeneralPathis a legacy final class which exactly implements the behavior of its superclassPath2D.Float. Together withPath2D.Double, thePath2Dclasses provide full implementations of a general geometric path that support all of the functionality of theShapeandPathIteratorinterfaces with the ability to explicitly select different levels of internal coordinate precision.Use
Path2D.Float(or this legacyGeneralPathsubclass) when dealing with data that can be represented and used with floating point precision. UsePath2D.Doublefor data that requires the accuracy or range of double precision.- Since:

Constructor Detail
GeneralPath
public GeneralPath()
Constructs a new empty single precisionGeneralPathobject with a default winding rule ofPath2D.WIND_NON_ZERO.- Since:
- 1.2
GeneralPath
public GeneralPath(int rule)
Constructs a newGeneralPathobject 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 newGeneralPathobject 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 rule -
initialCapacity- the estimate for the number of path segments in the path - Since:
- 1.2
- See Also:
-
Path2D.WIND_EVEN_ODD,Path2D.WIND_NON_ZERO
