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.

Field Details

id

protected String id

The control's object identifier string.

criticality

protected boolean criticality

The control's criticality.

value

protected byte[] value

The control's ASN.1 BER encoded value.

Constructor Details

BasicControl

public BasicControl(String id)

Constructs a non-critical control.

Parameters:

id - The control's object identifier string.

BasicControl

public BasicControl(String id,
 boolean criticality,
 byte[] value)

Constructs a control using the supplied arguments.

Parameters:

id - The control's object identifier string.

criticality - The control's criticality.

value - The control's ASN.1 BER encoded value. It is not cloned - any changes to value will affect the contents of the control. It may be null.

Method Details

getID

public String getID()

Retrieves the control's object identifier string.

Specified by:

getID in interface Control

Returns:

The non-null object identifier string.

isCritical

public boolean isCritical()

Determines the control's criticality.

Specified by:

isCritical in interface Control

Returns:

true if the control is critical; false otherwise.

getEncodedValue

public byte[] getEncodedValue()

Retrieves the control's ASN.1 BER encoded value. The result includes the BER tag and length for the control's value but does not include the control's object identifier and criticality setting.

Specified by:

getEncodedValue in interface Control

Returns:

A possibly null byte array representing the control's ASN.1 BER encoded value. It is not cloned - any changes to the returned value will affect the contents of the control.
