public class BasicControlDecorator<E>
extends ControlDecorator<Control>

A decorator for handling opaque Control objects where we know nothing about their encoded value. These Controls are generated by default when an ControlFactory for them has not been registered with the LdapCodecService.

Constructor Detail

BasicControlDecorator

public BasicControlDecorator(LdapCodecService codec,
                             Control control)

Creates a new instance of BasicControlDecorator, decorating a AbstractControl.

Parameters:

codec - The LDAP codec service.

control - The AbstractControl to decorate.

Method Detail

decode

public Asn1Object decode(byte[] controlBytes)
                  throws DecoderException

Decodes raw ASN.1 encoded bytes into an Asn1Object for the control.

Parameters:

controlBytes - the encoded control bytes

Returns:

the decoded Asn1Object for the control

Throws:

DecoderException - if anything goes wrong

computeLength

public int computeLength()

Compute the object length, which is the sum of all inner length.

Specified by:

computeLength in interface Asn1Object

Specified by:

computeLength in interface Decorator<Control>

Overrides:

computeLength in class ControlDecorator<Control>

Returns:

The object's computed length

encode

public ByteBuffer encode(ByteBuffer buffer)
                  throws EncoderException

Encode the object to a PDU.

Specified by:

encode in interface Asn1Object

Specified by:

encode in interface Decorator<Control>

Overrides:

encode in class AbstractAsn1Object

Parameters:

buffer - The buffer where to put the PDU

Returns:

The PDU.

Throws:

EncoderException - if the buffer can't be encoded
