GeneralPath (Java SE 19 & JDK 19)

All Implemented Interfaces:

Shape, Serializable, Cloneable

The

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.

    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.

    Parameters:

    rule - the winding rule

    Throws:

    IllegalArgumentException - if rule is not either Path2D.WIND_EVEN_ODD or Path2D.WIND_NON_ZERO

    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 - the winding rule

    initialCapacity - the estimate for the number of path segments in the path

    Throws:

    IllegalArgumentException - if rule is not either Path2D.WIND_EVEN_ODD or Path2D.WIND_NON_ZERO

    NegativeArraySizeException - if initialCapacity is negative

  • GeneralPath public GeneralPath(Shape s)

    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

    Throws:

    NullPointerException - if s is null
