public class IA5String

extends ASN1String

This class implements the native ASN.1 type "IA5String". IA5String is a simple ASN.1 string type identified by the UNIVERSAL TAG number 22.

An ASN.1 IA5String object may represent any arbitrary string of ASCII characters. The term IA5 denotes International Alphabet 5 (= ASCII).

When creating a new IA5String object the value to be represented has to be supplied as Java String type:

 String s = ...;
 IA5String ia5String = new IA5String(s);
 

Attention: When supplying the string value to be represented, no check is performed if it actually is composed only of characters belonging to IA5String character set! An application itself has to take care for supplying a proper IA5String value.

When calling the getValue method for getting the inherent string value from an ASN.1 IA5String instance, a Java object of type String is returned:

 String s = (String)ia5String.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

IA5String

protected IA5String()

Creates an empty IA5String.

IA5String

public IA5String(String value)

Creates a new ASN.1 IA5String 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 IA5String character set! An application itself has to take care for supplying a proper IA5String value.

Parameters:

value - the String value this IA5String object should be initialized with

Method Detail

getValue

public Object getValue()

Returns the value of this IA5String as a String object.

Overrides:

getValue in class ASN1Object

Returns:

the value of this IA5String as a String object

setValue

public void setValue(Object object)

Sets the value of this IA5String.

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 IA5String character set! An application itself has to take care for supplying a proper IA5String value.

Overrides:

setValue in class ASN1Object

Parameters:

object - the Java String value to be set for this IA5String
