Interface SecpPoint

All Known Subinterfaces:

SecpPoint.Compressed, SecpPoint.Point, SecpPoint.Uncompressed

All Known Implementing Classes:

SecpECPoint, SecpPoint.Infinity, SecpPointCompressed, SecpPointImpl, SecpPointUncompressed

public interface SecpPoint

A P256K1 point -- either SecpPoint.Compressed, SecpPoint.Uncompressed, or SecpPoint.Infinity. Implementations of this interface need not be subclasses of ECPoint. ECPoint is a concrete class and uses BigInteger internally. SecpPoint uses SecpFieldElement to represent point coordinates. If you need a type that is both a SecpPoint and a ECPoint, use SecpECPoint.
