Detailed Description

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).

Member Function Documentation

override void Decode

(

Asn1PerDecodeBuffer

buffer

)

[virtual]

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 mValue public member list variable. The public member variable choiceIndex will be populated with the decoded choice index value.

Parameters:

buffer

Decode message buffer object

Reimplemented from Asn1OpenType.

override void Decode	(	Asn1BerDecodeBuffer	buffer,
		bool	explicitTagging,
		int	implicitLength
	)			[virtual]

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

Parameters:

	buffer	Decode message buffer object
	explicitTagging	Flag indicating element is explicitly tagged
	implicitLength	Length of contents if implicit

Reimplemented from Asn1OpenType.

override void Encode

(

Asn1OerEncodeBuffer

buffer

)

[virtual]

Encode this unknown choice extension using the Octet Encoding Rules (OER). This uses this object's tag as the tag, and then encodes the value field as open type content.

Reimplemented from Asn1OpenType.

override void Encode

(

Asn1PerOutputStream

outs

)

[virtual]

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

Parameters:

outs

PER Output Stream object

Reimplemented from Asn1OpenType.

override void Encode	(	Asn1BerOutputStream	outs,
		bool	explicitTagging
	)			[virtual]

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

Parameters:

	outs	BER Output Stream object
	explicitTagging	Flag indicating element is explicitly tagged

Reimplemented from Asn1OpenType.

override void Encode

(

Asn1PerEncodeBuffer

buffer

)

[virtual]

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

Parameters:

buffer

Encode message buffer object

Reimplemented from Asn1OpenType.

override int Encode	(	Asn1BerEncodeBuffer	buffer,
		bool	explicitTagging
	)			[virtual]

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

Parameters:

	buffer	Encode message buffer object
	explicitTagging	Flag indicating element is explicitly tagged

Returns:

Length of encoded component

Reimplemented from Asn1OpenType.

Member Data Documentation

short choiceIndex

The choice index value is used with the packed encoding rules (PER) when this object is used to encode/Decode a choice extension.

Asn1Tag tag = null

tag is used with OER. When decoding, it should be set to hold the decoded tag. When encoding, it is encoded as the tag for the unknown choice extension. The form (tag.mForm) is irrelevant.
