OpenJDK 27 · java.awt.geom.GeneralPath · APIdia, the JavaDoc alternative

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

Access	Constructor and Description
public	GeneralPath() Constructs a new empty single precision `GeneralPath` object with a default winding rule of `WIND_NON_ZERO`.
public	GeneralPath(int the winding rule 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 the winding rule rule, int the estimate for the number of path segments in the path initialCapacity) Constructs a new `GeneralPath` object with the specified winding rule and the specified initial capacity to store path coordinates.
public	GeneralPath(Shape the specified `Shape` object s) Constructs a new `GeneralPath` object from an arbitrary `Shape` object.

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. 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:int: the winding rule
initialCapacity:int: the estimate for the number of path segments in the path

Exceptions

IllegalArgumentException:: if rule is not either WIND_EVEN_ODD or WIND_NON_ZERO
NegativeArraySizeException:: if initialCapacity is negative
