public class Asn1ChoiceExt

extends Asn1OpenType

This is a container class for holding a CHOICE open type extension element. This class is used for an open type extension (i.e. a ... at the end of a constructed type or a ..., ... at some other point in a constructed type).

Method Detail

decode

public void decode(Asn1BerDecodeBuffer buffer,
                   boolean explicit,
                   int implicitLength)
            throws Asn1Exception,
                   java.io.IOException

This method decodes an extension field using the Basic Encoding Rules (BER).

Specified by:

decode in interface Asn1TypeIF

Overrides:

decode in class Asn1OpenType

Parameters:

buffer - Decode message buffer object

explicit - Flag indicating element is explicitly tagged

implicitLength - Length of contents if implicit

Throws:

Asn1Exception

java.io.IOException

encode

public int encode(Asn1BerEncodeBuffer buffer,
                  boolean explicit)
           throws Asn1Exception

This method encodes an ASN.1 open type extension value using the Basic Encoding Rules (BER).

Specified by:

encode in interface Asn1TypeIF

Overrides:

encode in class Asn1OpenType

Parameters:

buffer - Encode message buffer object

explicit - Flag indicating element is explicitly tagged

Returns:

Length of encoded component

Throws:

Asn1Exception

decode

public void decode(Asn1PerDecodeBuffer buffer)
            throws Asn1Exception,
                   java.io.IOException

This method decodes an open type extension in a CHOICE construct using the packed encoding rules (PER). This method will capture the extension item in an open type object and store it in the value public member list variable. The public member variable choiceIndex will be populated with the decoded choice index value.

Specified by:

decode in interface Asn1TypeIF

Overrides:

decode in class Asn1OctetString

Parameters:

buffer - Decode message buffer object

Throws:

Asn1Exception

java.io.IOException

encode

public void encode(Asn1PerEncodeBuffer buffer)
            throws Asn1Exception,
                   java.io.IOException

This method encodes an ASN.1 open type extension value using the Packed Encoding Rules (PER).

Specified by:

encode in interface Asn1TypeIF

Overrides:

encode in class Asn1OpenType

Parameters:

buffer - Encode message buffer object

Throws:

Asn1Exception

java.io.IOException

encode

public void encode(Asn1BerOutputStream out,
                   boolean explicit)
            throws Asn1Exception,
                   java.io.IOException

This method encodes an ASN.1 open type extension value using the Basic Encoding Rules (BER).

Specified by:

encode in interface Asn1TypeIF

Overrides:

encode in class Asn1OpenType

Parameters:

out - BER Output Stream object

explicit - Flag indicating element is explicitly tagged

Throws:

java.io.IOException - Any exception thrown by the underlying OutputStream.

Asn1Exception - Thrown, if operation is failed.

encode

public void encode(Asn1PerOutputStream out)
            throws Asn1Exception,
                   java.io.IOException

This method encodes an ASN.1 open type value using the Packed Encoding Rules (PER).

Specified by:

encode in interface Asn1TypeIF

Overrides:

encode in class Asn1OpenType

Parameters:

out - PER Output Stream object

Throws:

java.io.IOException - Any exception thrown by the Asn1PerOutputStream.

Asn1Exception - Thrown, if operation is failed.
