java.security.spec.ECPoint
This immutable class represents a point on an elliptic curve (EC) in affine coordinates. Other coordinate systems can extend this class to represent this point in other coordinates. @author Valerie Peng @version 1.4, 11/17/05 @since 1.5
org.bouncycastle.math.ec.ECPoint
base class for points on elliptic curves.
