iaik.asn1.NumericString

public class NumericString
extends ASN1String

This class implements the native ASN.1 type "NumericString". NumericString is a simple ASN.1 string type identified by the UNIVERSAL TAG number 18.

An ASN.1 NumericString object may represent any arbitrary string of numeric characters including the space character: 0,1,2,...,9,SPACE

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

 String s = ...;
 NumericString numericString = new NumericString(s);
 

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

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

 String s = (String)numericString.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

NumericString

protected NumericString()

Creates an empty NumericString.

NumericString

public NumericString(java.lang.String value)

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

Parameters:

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

Method Detail

getValue

public java.lang.Object getValue()

Returns the value of this NumericString as a String.

Specified by:

getValue in class ASN1Object

Returns:

the value of this NumericString as a String object

setValue

public void setValue(java.lang.Object object)

Sets the value of this NumericString.

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

Specified by:

setValue in class ASN1Object

Parameters:

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