Detailed Description

This is a container class for holding the components of an ASN.1 UTC time string value.

---

Constructor & Destructor Documentation

Asn1UTCTime

(

)

The default constructor creates an empty time string object.

Asn1UTCTime

(

bool

useDerRules

)

This constructor creates an empty UTCTime string object and allows DER encoding rules to be specified.

Parameters:

useDerRules

'true' if time string should be encoded with DER/PER.

Asn1UTCTime

(

System.String

data

)

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

Parameters:

data

UTCTime as string

Asn1UTCTime	(	System.String	data,
		bool	useDerRules
	)

This version of the constructor can be used to set the string mValue member variable to the given time string and specify DER encoding rules be used to construct the string.

Parameters:

	data	UTCTime as string
	useDerRules	'true' if time string should be encoded with DER/PER.

Member Function Documentation

override void Clear

(

)

[virtual]

Clears out time string.

Reimplemented from Asn1Time.

override System.Int32 CompareTo

(

System.Object

obj

)

[virtual]

This method compares this object with Asn1Time class instance or with System.DateTime instance. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. Note that the action of this method may differentiate for different inherited Asn1Time classes.

Parameters:

obj

the Object to be compared.

Returns:

The difference in Ticks with the specified object.

Reimplemented from Asn1Time.

internal override bool CompileString

(

)

[protected, virtual]

Compiles new time string accoring X.680 (clause 42) and ISO 8601.

Returns:

true if successful; otherwise false.

Implements Asn1Time.

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

This method decodes an ASN.1 UTCTime 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 UTC time 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.

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

This method encodes an ASN.1 UTCTime 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.

internal override void Init

(

)

[protected, virtual]

This method initializes the Asn1UTCTime class member variables.

Reimplemented from Asn1Time.

override void ParseString

(

System.String

data

)

[virtual]

This method parses passed UTCTime string.

Parameters:

data

The UTCTime string value to be parsed.

Exceptions:

Asn1Exception

Thrown, if operation is failed.

Implements Asn1Time.

override void SetTime

(

System.DateTime

time

)

[virtual]

This method converts the System.DateTime value to UTCTime string.

Parameters:

time

The System.DateTime value.

Exceptions:

Asn1Exception

Thrown, if operation is failed.

Reimplemented from Asn1Time.

Member Data Documentation

new readonly Asn1Tag _TAG [static]

The _TAG constant describes the universal tag for this data type (UNIVERSAL 23).

Reimplemented from Asn1Type.

---

Property Documentation

override string Fraction [get, set]

Gets the Fraction component of the UTC Time. Which is always Zero(i.e. empty string)

Value: Zero or empty string

Exceptions:

Asn1Exception

Always thrown for Sets call.

Reimplemented from Asn1Time.

override int Year [get, set]

Gets or Sets the year component of the time value. You may pass 'year' parameter either as two last digits of the year (00 - 99) or as full 4 digits (0 - 9999). Note Gets returns year in full 4 digits format.

Value: Year component (full 4 digits).

Exceptions:

Asn1Exception

Thrown, if operation is failed.

Reimplemented from Asn1Time.
