Field Detail

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 Detail

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 Detail

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.
