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).

For BER, data is expected to be a full TLV. For PER, data is the encoding of the actual type; choiceIndex is the PER choice index. For OER, data is the encoding of the actual type; tag is the OER tag.

Constructor & Destructor Documentation

Asn1ChoiceExt() [1/3]

Asn1ChoiceExt

(

)

This constructor creates an empty type that can be used in a Decode method call to receive an encoded value. The data encoding is UNKNOWN.

Asn1ChoiceExt() [2/3]

Asn1ChoiceExt

(

byte []

data

)

This constructor initializes an open type from the given byte array. The array is assumed to contain a previously encoded message component. The data encoding is UNKNOWN.

Parameters

data	Byte array containing a previously encoded message component.

Asn1ChoiceExt() [3/3]

Asn1ChoiceExt	(	byte []	data,
		int	encoding
	)

This constructor initializes an open type from the given byte array. The array is assumed to contain a previously encoded message component.

Parameters

data	Byte array containing a previously encoded value.
encoding	The encoding that describes the meaning of data. Any of the encodings other than JSON.

Member Function Documentation

Decode() [1/2]

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 Asn1Type.

Decode() [2/2]

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 Asn1Type.

References Asn1PerDecodeBuffer.DecodeSmallNonNegWholeNumber().

Encode() [1/5]

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 Asn1Type.

Encode() [2/5]

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 Asn1Type.

References Asn1PerOutputStream.EncodeOpenType(), and Asn1PerEncodeBuffer.EncodeSmallNonNegWholeNumber().

Encode() [3/5]

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 Asn1Type.

Encode() [4/5]

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 Asn1Type.

Encode() [5/5]

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 Asn1Type.

Member Data Documentation

choiceIndex

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.

tag

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.
