Constructor & Destructor Documentation

Asn1NumericString

(

)

The default constructor creates an empty string object.

Asn1NumericString

(

data

)

This version of the constructor can be used to set the string mValue member variable to the given string value.

Parameters:

data

string representation of numeric string

Member Function Documentation

virtual void Decode	(	Asn1PerDecodeBuffer	buffer,
		long	lower,
		long	upper
	)			[virtual]

This overloaded version of the Decode method decodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes a size constraint is present but no permitted alphabet constraint.

The decoded result is stored in the public mValue member variable in the Asn1CharString base class.

Parameters:

	buffer	Decode message buffer object
	lower	Effective size constraint lower bound
	upper	Effective size constraint upper bound

override void Decode

(

Asn1PerDecodeBuffer

buffer

)

[virtual]

This method decodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes no permitted alphabet or size constraints. Decoded characters are assigned as-is to the output string. The decoded result is stored in the public mValue member variable in the Asn1CharString base class.

Parameters:

buffer

Decode message buffer object

Reimplemented from Asn18BitCharString.

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

This method decodes an ASN.1 string value including the UNIVERSAL tag value and length if explicit tagging is specified.

Parameters:

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

Reimplemented from Asn1Type.

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

This method encodes and writes to the stream an ASN.1 numeric string value including the UNIVERSAL tag value and length if explicit tagging is specified. This overloaded version uses the Basic Encoding Rules (BER).

Throws, Exception thrown by C# System.IO.Stream for I/O error

Parameters:

	outs	BER Output Stream object
	explicitTagging	Flag indicating explicit tagging should be done

Exceptions:

Asn1Exception

Thrown, if operation is failed.

Reimplemented from Asn1Type.

virtual void Encode	(	Asn1PerEncodeBuffer	buffer,
		long	lower,
		long	upper
	)			[virtual]

This overloaded version of the encode method encodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes a size constraint is present but no permitted alphabet constraint.

The value to encode is stored in the public mValue member variable in the Asn1CharString base class.

Parameters:

	buffer	Encode message buffer object
	lower	Effective size constraint lower bound
	upper	Effective size constraint upper bound

override void Encode

(

Asn1PerEncodeBuffer

buffer

)

[virtual]

This method encodes an ASN.1 character string value in accordance with the packed encoding rules (PER). This version of the method assumes no permitted alphabet or size constraints.

The value to encode is stored in the public mValue member variable in the Asn1CharString base class.

Parameters:

buffer

Encode message buffer object

Reimplemented from Asn18BitCharString.

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

This method encodes an ASN.1 string type. The UNIVERSAL tag value and length is also encoded if explicit tagging is specified.

Parameters:

	buffer	Encode message buffer object
	explicitTagging	Flag indicating explicit tagging should be done

Returns:

Length in octets of encoded component

Reimplemented from Asn1Type.
