From class java.lang.Object

Object	clone() Returns 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 returns true if they represent the same object using a class specific comparison.
void	finalize() Called by the virtual machine when there are no longer any (non-weak) references to the receiver.
final Class<? extends Object>	getClass() Returns the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode() Returns an integer hash code for the receiver.
final void	notify() Causes one thread which is `wait` ing on the receiver to be made ready to run.
final void	notifyAll() Causes all threads which are `wait` ing on the receiver to be made ready to run.
String	toString() Returns a string containing a concise, human-readable description of the receiver.
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.
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() 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`).

Public Methods

public Object clone ()

Returns 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.

Classes which wish to support cloning must specify that they implement the Cloneable interface, since the implementation checks for this.

Returns

Object a shallow copy of this object.

Throws

CloneNotSupportedException

public final String getAlgorithm ()

public static Signature getInstance (String algorithm, String provider)

Throws

NoSuchAlgorithmException
NoSuchProviderException

public static Signature getInstance (String algorithm)

Throws

NoSuchAlgorithmException

public static Signature getInstance (String algorithm, Provider provider)

Throws

NoSuchAlgorithmException

public final Object getParameter (String param)

This method is deprecated.There is no generally accepted parameter naming convention.

public final void initVerify (Certificate certificate)

Throws

public final void setParameter (String param, Object value)

This method is deprecated.Use setParameter

@com.intel.drl.spec_ref

Throws

public final byte[] sign ()

Throws

SignatureException

Returns a string containing a concise, human-readable description of the receiver.

Returns

String a printable representation for the receiver.

public final void update (byte[] data)

Throws

SignatureException

public final void update (byte b)

Throws

SignatureException

public final void update (byte[] data, int off, int len)
