All Implemented Interfaces:

DEREncodable

public class Targets
extends ASN1Encodable

Targets structure used in target information extension for attribute certificates from RFC 3281.

            Targets ::= SEQUENCE OF Target
 

            Target  ::= CHOICE {
              targetName          [0] GeneralName,
              targetGroup         [1] GeneralName,
              targetCert          [2] TargetCert
            }
 

            TargetCert  ::= SEQUENCE {
              targetCertificate    IssuerSerial,
              targetName           GeneralName OPTIONAL,
              certDigestInfo       ObjectDigestInfo OPTIONAL
            }

Constructor Detail

Targets

private Targets(ASN1Sequence targets)

Constructor from ASN1Sequence.

Parameters:

targets - The ASN.1 SEQUENCE.

Targets

public Targets(Target[] targets)

Constructor from given targets.

The vector is copied.

Parameters:

targets - A Vector of Targets.

getInstance

public static Targets getInstance(java.lang.Object obj)

Creates an instance of a Targets from the given object.

obj can be a Targets or a ASN1Sequence

Parameters:

obj - The object.

Returns:

A Targets instance.

Throws:

java.lang.IllegalArgumentException - if the given object cannot be interpreted as Target.

getTargets

public Target[] getTargets()

Returns the targets in a Vector.

The vector is cloned before it is returned.

Returns:

Returns the targets.

toASN1Object

public DERObject toASN1Object()

Produce an object suitable for an ASN1OutputStream.

Returns:

            Targets ::= SEQUENCE OF Target
 

Specified by:

toASN1Object in class ASN1Encodable

Returns:

a DERObject
