public class T61String
extends ASN1String

This class implements the native ASN.1 type "T61String" (TeletexString). T61String is a simple ASN.1 string type identified by the UNIVERSAL TAG number 20.

An ASN.1 T61String object may represent any arbitrary string of T.61 (eight-bit extension of the ASCII character set) characters. The T61String character set is defined by CCITT Recommendation T.61.

When creating a new T61String object the value to be represented has to be supplied as Java String type:

 String s = ...;
 T61String t61String = new T61String(s);
 

Attention: When supplying the string value to be represented, no check is performed if it actually is composed only of characters belonging to T61String character set! An application itself has to take care for supplying a proper T61String value.

When calling the getValue method for getting the inherent string value from an ASN.1 T61String instance, a Java object of type String is returned:

 String s = (String)t61String.getValue();
 

DER en/decoding generally is done by means of the several methods of the DerCoder class; decoding alternatively may be performed by using the DerInputStream utility.

Constructor Detail

T61String

protected T61String()

Creates an empty T61String object.

T61String

public T61String(java.lang.String value)

Creates a new ASN.1 T61String object for the given String value.

Attention: No check is performed if the supplied String value actually is composed only of characters belonging to the T61String character set! An application itself has to take care for supplying a proper T61String value.

Parameters:

value - the String value this T61String object should be initialized with

Method Detail

getValue

public java.lang.Object getValue()

Returns the value of this T61String as a String object.

Specified by:

getValue in class ASN1Object

Returns:

the value of this T61String as a String object

setValue

public void setValue(java.lang.Object object)

Sets the value of this T61String.

The supplied value has to be a Java object of type String. Attention: No check is performed if the supplied String value actually is composed only of characters belonging to T61String character set! An application itself has to take care for supplying a proper T61String value.

Specified by:

setValue in class ASN1Object

Parameters:

object - the Java String value to be set for this T61String

countComponents

public int countComponents()

Components are not supported so we return 0

Overrides:

countComponents in class ASN1Object

Returns:

nothing, since this method only throws a CodingException
