NamedParameterSpec

public class NamedParameterSpec
extends Object implements AlgorithmParameterSpec

java.lang.Object
   ↳ java.security.spec.NamedParameterSpec
ECGenParameterSpec This immutable class specifies the set of parameters used for generating elliptic curve (EC) domain parameters. 


This class is used to specify any algorithm parameters that are determined by a standard name. This class also holds constants for standard parameter set names. The names of these constants exactly match the corresponding parameter set name. For example, NamedParameterSpec.X25519 represents the parameter set identified by the string "X25519". These strings are defined in the Java Security Standard Algorithm Names Specification.

Public methods

String getName()

Returns the standard name that determines the algorithm parameters.

Inherited methods

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
