java.awt.geom.GeneralPath
| GeneralPath | | final public class GeneralPath extends Path2D.Float (Code) | | The
GeneralPath 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 superclass
Path2D.Float .
Together with
Path2D.Double , the
Path2D classes
provide full implementations of a general geometric path that
support all of the functionality of the
Shape and
PathIterator interfaces with the ability to explicitly
select different levels of internal coordinate precision.
Use
Path2D.Float (or this legacy
GeneralPath subclass) when dealing with data that can be represented
and used with floating point precision. Use
Path2D.Double for data that requires the accuracy or range of double precision.

| Constructor Summary | |
| public | GeneralPath()
Constructs a new empty single precision
GeneralPath object
with a default winding rule of
GeneralPath.WIND_NON_ZERO . | | public | GeneralPath(int rule)
Constructs a new GeneralPath object with the specified
winding rule to control operations that require the interior of the
path to be defined. | | public | GeneralPath(int rule, int initialCapacity)
Constructs a new GeneralPath object with the specified
winding rule and the specified initial capacity to store path
coordinates. | | public | GeneralPath(Shape s)
Constructs a new GeneralPath object from an arbitrary
Shape object. | | | GeneralPath(int windingRule, byte[] pointTypes, int numTypes, float[] pointCoords, int numCoords)
|
| GeneralPath | | public GeneralPath()(Code) | | Constructs a new empty single precision
GeneralPath object
with a default winding rule of
GeneralPath.WIND_NON_ZERO .

| GeneralPath | | public GeneralPath(int rule)(Code) | | Constructs a new GeneralPath object with the specified
winding rule to control operations that require the interior of the
path to be defined.
Parameters:
rule - the winding rule
See Also: GeneralPath.WIND_EVEN_ODD
See Also: GeneralPath.WIND_NON_ZERO
since:
1.2 |
| GeneralPath | | public GeneralPath(int rule, int initialCapacity)(Code) | | Constructs a new GeneralPath 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 rule
Parameters:
initialCapacity - the estimate for the number of path segmentsin the path
See Also: GeneralPath.WIND_EVEN_ODD
See Also: GeneralPath.WIND_NON_ZERO

| GeneralPath | | public GeneralPath(Shape s)(Code) | | Constructs a new GeneralPath object from an arbitrary
Shape object.
All of the initial geometry and the winding rule for this path are
taken from the specified Shape object.
Parameters:
s - the specified Shape object
