Constructor Summary

Constructors

Constructor	Description
ECGenParameterSpec(String stdName)	Creates a parameter specification for EC parameter generation using a standard (or predefined) name stdName in order to generate the corresponding (precomputed) elliptic curve domain parameters.

Method Summary

getName

Modifier and Type	Method	Description
String	getName()	Returns the standard name that determines the algorithm parameters.

Methods declared in class Object

clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

Modifier and Type	Method	Description
protected Object	clone()	Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
boolean	equals(Object o)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode()	Answers an integer hash code for the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
String	toString()	Answers a string containing a concise, human-readable description of the receiver.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Constructor Details

ECGenParameterSpec

public ECGenParameterSpec(String stdName)

Creates a parameter specification for EC parameter generation using a standard (or predefined) name stdName in order to generate the corresponding (precomputed) elliptic curve domain parameters. For the list of supported names, please consult the documentation of the provider whose implementation will be used.

Parameters:

stdName - the standard name of the to-be-generated EC domain parameters. See the ECGenParameterSpec section in the Java Security Standard Algorithm Names Specification for information about standard names.

Throws:

NullPointerException - if stdName is null.
