Member Function Documentation
| virtual void Decode | ( | Asn1JsonDecodeBuffer | buffer | ) | [virtual] |
Decode ASN.1 NULL from JSON.
| override void Decode | ( | Asn1PerDecodeBuffer | buffer | ) | [virtual] |
This method decodes an ASN.1 null value in accordance with the Packed Encoding Rules (PER).
- Parameters:
-
buffer Decode message buffer object
Reimplemented from Asn1Type.
| override void Decode | ( | Asn1BerDecodeBuffer | buffer, | |
| bool | explicitTagging, | |||
| int | implicitLength | |||
| ) | [virtual] |
This method decodes an ASN.1 null value including the UNIVERSAL tag value and length if explicit tagging is specified. This overloaded version uses 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.
| virtual void DecodeXER | ( | System.String | buffer, | |
| System.String | attrs | |||
| ) | [virtual] |
This method decodes an ASN.1 null value using the XML encoding rules (XER).
- Parameters:
-
buffer String containing data to be decoded attrs Attributes string from element tag
| override void DecodeXML | ( | System.String | buffer, | |
| System.String | attrs | |||
| ) |
This method decodes an ASN.1 null value using the XML schema encoding rules(asn2xsd).
- Parameters:
-
buffer String containing data to be decoded attrs Attributes string from element tag
| override void Encode | ( | Asn1PerOutputStream | outs | ) | [virtual] |
This method encodes an ASN.1 null value in accordance with the Packed Encoding Rules (PER).
Also throws any exception thrown by the underlying Asn1PerOutputStream.
- Parameters:
-
outs PER Output Stream object
- Exceptions:
-
Asn1Exception Thrown, if operation is failed.
Reimplemented from Asn1Type.
| override void Encode | ( | Asn1BerOutputStream | outs, | |
| bool | explicitTagging | |||
| ) | [virtual] |
This method encodes and writes to the stream an ASN.1 NULL 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 | ( | Asn1JsonOutputStream | outstream | ) | [virtual] |
Encode this ASN.1 null value to JSON
| override void Encode | ( | Asn1XmlEncoder | buffer, | |
| System.String | elemName, | |||
| System.String | nsPrefix | |||
| ) | [virtual] |
This method encodes an ASN.1 null value using the XML Encoding as specified in the XML schema standard(asn2xsd).
- Parameters:
-
buffer Encode message buffer object elemName Element name nsPrefix Element namespace value
Reimplemented from Asn1Type.
| override void Encode | ( | Asn1XerEncoder | buffer, | |
| System.String | elemName | |||
| ) | [virtual] |
This method encodes an ASN.1 null value using the XML encoding rules (XER).
- Parameters:
-
buffer Encode message buffer object elemName Element name
Reimplemented from Asn1Type.
| override void Encode | ( | Asn1PerEncodeBuffer | buffer | ) | [virtual] |
This method encodes an ASN.1 null value in accordance with the Packed Encoding Rules (PER).
- Parameters:
-
buffer Encode message buffer object
Reimplemented from Asn1Type.
| override int Encode | ( | Asn1BerEncodeBuffer | buffer, | |
| bool | explicitTagging | |||
| ) | [virtual] |
This method encodes an ASN.1 null value including the UNIVERSAL tag value and length if explicit tagging is specified. This overloaded version used the Basic Encoding Rules (BER).
- Parameters:
-
buffer Encode message buffer object explicitTagging Flag indicating explicit tagging should be done
- Returns:
- Length (in octets) of encoded component
Reimplemented from Asn1Type.
| override bool Equals | ( | object | o | ) |
Tests for equality with any other object. Returns true if the input type is an Asn1Null object and false otherwise.
| override System.String ToString | ( | ) |
This method will return a string representation of the null value. The format is the ASN.1 value format for this type..
- Returns:
- Stringified representation of the value
