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 Asn1AbstractTime.

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 Asn1AbstractTime.

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 Asn1AbstractTime.

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 Asn1AbstractTime.

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 Asn1AbstractTime.

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 Asn1AbstractTime.

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 Asn1AbstractTime.

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 Asn1AbstractTime.
