public class ECPublicKeySpec
extends Object implements KeySpec

java.lang.Object
	java.security.spec.ECPublicKeySpec

这个不可变的类用相关的参数指定一个椭圆曲线公钥。

也可以看看：

Public constructors
`ECPublicKeySpec(ECPoint w, ECParameterSpec params)` 用指定的参数值创建一个新的ECPublicKeySpec。

公共方法(Public methods)
`ECParameterSpec`	`getParams()` 返回关联的椭圆曲线域参数。
`ECPoint`	`getW()` 返回公共点W.

ECPublicKeySpec (ECPoint w, 
                ECParameterSpec params)

用指定的参数值创建一个新的ECPublicKeySpec。

参数(Parameters)
`w`	`ECPoint`: the public point.
`params`	`ECParameterSpec`: the associated elliptic curve domain parameters.

抛出异常(Throws)
`NullPointerException`	if `w` or `params` is null.
`IllegalArgumentException`	if `w` is point at infinity, i.e. ECPoint.POINT_INFINITY
