public class GeneralString

extends ASN1String

This class implements the native ASN.1 type "GENERAL STRING". GeneralString is a simple ASN.1 string type identified by the UNIVERSAL TAG number 27.

The ASN.1 character string type GeneralString encompasses all registered graphic and character sets (see ISO 2375) plus SPACE and DELETE.

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

 String s = ...;
 GeneralString generalString = new GeneralString(s);
 

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

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

 String s = (String)generalString.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

GeneralString

protected GeneralString()

Creates an empty GeneralString.

GeneralString

public GeneralString(String value)

Creates a new ASN.1 GeneralString 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 GeneralString character set! An application itself has to take care for supplying a proper GeneralString value.

Parameters:

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

Method Detail

getValue

public Object getValue()

Returns the value of this GeneralString as a String object.

Overrides:

getValue in class ASN1Object

Returns:

the value of this GeneralString as a String object

setValue

public void setValue(Object object)

Sets the value of this GeneralString.

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 GeneralString character set! An application itself has to take care for supplying a proper GeneralString value.

Overrides:

setValue in class ASN1Object

Parameters:

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