Constructor & Destructor Documentation

Asn1NumericString  ) 
 

The default constructor creates an empty string object.

Asn1NumericString System.String  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.


Member Data Documentation

new readonly Asn1Tag _TAG [static]
 

The _TAG constant describes the universal tag for this data type (UNIVERSAL 18).

Reimplemented from Asn1Type.

readonly Asn1CharSet CHARSET [static]
 

Initial value:

 
         new Asn1DiscreteCharSet(" 0123456789")
The CHARSET constant specifies the character set for a numeric string in canonical order.
