public class VisibleString
extends ASN1String

This class implements the native ASN.1 type "VisibleString" (ISO646String). VisibleString is a simple ASN.1 string type identified by the UNIVERSAL TAG number 26.

The ASN.1 character string type VisibleString encompasses all visible characters of the IA5 (International Alphabet 5) character set.

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

 String s = ...;
 VisibleString visibleString = new VisibleString(s);
 

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

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

 String s = (String)visibleString.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

VisibleString

protected VisibleString()

Creates an empty VisibleString.

VisibleString

public VisibleString(java.lang.String value)

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

Parameters:

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

Method Detail

getValue

public java.lang.Object getValue()

Returns the value of this VisibleString as a String.

Specified by:

getValue in class ASN1Object

Returns:

the value of this VisibleString as a String object

setValue

public void setValue(java.lang.Object object)

Sets the value of this VisibleString.

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

Specified by:

setValue in class ASN1Object

Parameters:

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