public abstract class AbstractShape
extends Object
implements Shape

Base class for some (not all) shape implementations in Apache SIS. This base class provides a mechanism for determining if a shape stores coordinate values as simple-precision or double-precision floating point numbers.

FLOAT_SHAPES

private static final Class<?>[] FLOAT_SHAPES

Base classes of Java2D implementations known to store coordinates as single-precision floating point numbers.

Constructor Details

AbstractShape

protected AbstractShape()

Creates a new shape.

Method Details

isFloat

protected boolean isFloat()

Returns true if this shape backed by primitive float values.

Returns:

true if this shape is backed by float coordinate values.

isFloat

public static boolean isFloat(Object shape)

Returns true if the given shape is presumed backed by primitive float values. The given object should be an instance of Shape or Point2D.

Parameters:

shape - the shape for which to determine the backing primitive type.

Returns:

true if the given shape is presumed backed by float coordinate values.
