Detailed Description

This is a container class for holding the components of an ASN.1 object identifier value.

---

Constructor & Destructor Documentation

Asn1ObjectIdentifier

(

)

This constructor creates an empty object identifier that can be used in a Decode method call to receive an OID value.

Asn1ObjectIdentifier

(

int[]

value

)

This constructor initializes the object identifier from the given array of integer subidentifier values.

Parameters:

value

Array of subidentifiers

---

Member Function Documentation

virtual void Append

(

int[]

value2

)

[virtual]

This method appends an object identifier value onto the existing value. A typical use of this method would be for SNMP objects to create the base and index parts.

Parameters:

value2

Array of subidentifiers to append

override void Decode

(

Asn1PerDecodeBuffer

buffer

)

[virtual]

This method decodes an ASN.1 object identifier value using the packed encoding rules (PER).

Parameters:

buffer

Decode message buffer object

Reimplemented from Asn1Type.

Reimplemented in Asn1RelativeOID.

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

This method decodes an ASN.1 object identifier 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.

Reimplemented in Asn1RelativeOID.

virtual void DecodeXER	(	System.String	buffer,
		System.String	attrs
	)			[virtual]

This method decodes an ASN.1 object identifier value using the XML encoding rules (XER).

Parameters:

	buffer	String containing data to be decoded
	attrs	Attributes string from element tag

Reimplemented in Asn1RelativeOID.

override void DecodeXML	(	System.String	buffer,
		System.String	attrs
	)

This method decodes an ASN.1 object identifier value using the XML schema encoding rules(asn2xsd).

Parameters:

	buffer	String containing data to be decoded
	attrs	Attributes string from element tag

Reimplemented in Asn1RelativeOID.

override void Encode

(

Asn1PerOutputStream

outs

)

[virtual]

This method encodes an ASN.1 object identifier value using the packed encoding rules (PER).

The value to be encoded is stored in the mValue public member variable within this class.

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.

Reimplemented in Asn1RelativeOID.

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

This method encodes and writes to the stream an ASN.1 object identifier 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.

Reimplemented in Asn1RelativeOID.

virtual void Encode	(	Asn1XmlEncoder	buffer,
		System.String	elemName,
		System.String	nsPrefix
	)			[virtual]

This method encodes an ASN.1 object identifier 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 in Asn1RelativeOID.

override void Encode	(	Asn1XerEncoder	buffer,
		System.String	elemName
	)			[virtual]

This method encodes an ASN.1 object identifier value using the XML encoding rules (XER).

Parameters:

	buffer	Encode message buffer object
	elemName	Element name

Reimplemented from Asn1Type.

Reimplemented in Asn1RelativeOID.

override void Encode

(

Asn1PerEncodeBuffer

buffer

)

[virtual]

This method encodes an ASN.1 object identifier value using the packed encoding rules (PER).

The value to be encoded is stored in the mValue public member variable within this class.

Parameters:

buffer

Encode message buffer object

Reimplemented from Asn1Type.

Reimplemented in Asn1RelativeOID.

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

This method encodes an ASN.1 object identifier value including the UNIVERSAL tag value and length if explicit tagging is specified.

Parameters:

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

Returns:

Length of encoded component in octets

Reimplemented from Asn1Type.

Reimplemented in Asn1RelativeOID.

override bool Equals

(

System.Object

value

)

This method compares this object identifier to the given one for equality.

Parameters:

value

The Object to compare with the current Object. Object should be instance of Asn1ObjectIdentifier.

Returns:

true if the specified Object is equal to the current Object; otherwise, false.

override int GetHashCode

(

)

Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table.

Returns:

A hash code for the current Object.

override System.String ToString

(

)

This method will return a string representation of the OID value. The format is the ASN.1 value format for this type. Note that textual subidentifiers are not used, only numeric values..

Returns:

Stringified representation of the value

Member Data Documentation

new readonly Asn1Tag _TAG [static]

The _TAG constant describes the universal tag for this data type (UNIVERSAL 6).

Reimplemented from Asn1Type.

Reimplemented in Asn1RelativeOID.

const int MAXSUBIDS = 128

The MAXSUBIDS constant specifies the maximum number of subidentifiers that can appear in an OID value (128).

int [] mValue

The mValue public member variable is where the object identifier value is stored.
