Field Detail

TAG

public static final Asn1Tag TAG

The TAG constant describes the universal tag for this data type (UNIVERSAL 24).

Constructor Detail

Asn1GeneralizedTime

public Asn1GeneralizedTime()

The default constructor creates an empty time string object.

Asn1GeneralizedTime

public Asn1GeneralizedTime(boolean useDerRules)

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

Parameters:

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

Asn1GeneralizedTime

public Asn1GeneralizedTime(java.lang.String data)

This version of the constructor can be used to set the string value member variable to the given time string. The format of a GeneralizedTime string is YYYYMMDDHHMMSS.n[Z][-HHMM].

Parameters:

data - Character string

Asn1GeneralizedTime

public Asn1GeneralizedTime(java.lang.String data,
                           boolean useDerRules)

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

Parameters:

data - Character string

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

Method Detail

equals

public boolean equals(java.lang.String s)

This method compares this object with a String value. Strictly speaking, the contract of equals stipulates identity: a.equals(b) iff b.equals(a). However, it is never the case that a String will equal an Asn1Time object. In this case, then, equals should be taken to mean that the time represented by the string passed in is the same time as the object to which it is compared.

Specified by:

equals in class Asn1Time

Parameters:

s -

decode

public void decode(Asn1BerDecodeBuffer buffer,
                   boolean explicit,
                   int implicitLength)
            throws Asn1Exception,
                   java.io.IOException

This method decodes an ASN.1 string value including the UNIVERSAL tag value and length if explicit tagging is specified.

Specified by:

decode in interface Asn1TypeIF

Overrides:

decode in class Asn1Type

Parameters:

buffer - Decode message buffer object

explicit - Flag indicating element is explicitly tagged

implicitLength - Length of contents if implicit

Throws:

Asn1Exception

java.io.IOException

encode

public int encode(Asn1BerEncodeBuffer buffer,
                  boolean explicit)
           throws Asn1Exception

This method encodes an ASN.1 string type. The UNIVERSAL tag value and length is also encoded if explicit tagging is specified.

Specified by:

encode in interface Asn1TypeIF

Overrides:

encode in class Asn1Type

Parameters:

buffer - Encode message buffer object

explicit - Flag indicating explicit tagging should be done

Returns:

Length in octets of encoded component

Throws:

Asn1Exception

getCentury

public int getCentury()
               throws Asn1Exception

This method returns the century part (first two digits) of the year component of the time value.

Returns:

Century part (first two digits) of the year component is returned if the operation is successful.

Throws:

Asn1Exception - Thrown, if operation is failed.

setCentury

public void setCentury(int century)
                throws Asn1Exception

This method sets the century part (first two digits) of the year component of the time value.

Parameters:

century - Century part (first two digits) of the year component.

Throws:

Asn1Exception - Thrown, if operation is failed.

parseString

public void parseString(java.lang.String string)
                 throws Asn1Exception

This method parses the given time string value. It will throw and exception if the string is not in the valid time format. The valid format of a GeneralizedTime string is YYYYMMDDHHMMSS.n[Z][-HHMM].

Specified by:

parseString in class Asn1Time

Parameters:

string - The time string value to be parsed.

Throws:

Asn1Exception - Thrown, if operation is failed.

compileString

protected boolean compileString()
                         throws Asn1Exception

Compiles new time string accoring X.680 (clause 41) and ISO 8601.

Specified by:

compileString in class Asn1Time

Returns:

true, if succeed, or false code, if error.

Throws:

Asn1Exception - Thrown, if operation is failed.

encode

public void encode(Asn1BerOutputStream out,
                   boolean explicit)
            throws Asn1Exception,
                   java.io.IOException

This method encodes and writes to stream an ASN.1 generalized time string value including the UNIVERSAL tag value and length if explicit tagging is specified. This overloaded version uses the Basic Encoding Rules (BER).

Specified by:

encode in interface Asn1TypeIF

Overrides:

encode in class Asn1Type

Parameters:

out - BER Output Stream object

explicit - Flag indicating explicit tagging should be done

Throws:

java.io.IOException - Any exception thrown by the underlying OutputStream.

Asn1Exception - Thrown, if operation is failed.
