Class Attributes

java.lang.Object

org.bouncycastle.asn1.ASN1Object

org.bouncycastle.asn1.cms.Attributes

All Implemented Interfaces:

ASN1Encodable, Encodable

public class Attributes
extends ASN1Object

RFC 5652 defines 5 "SET OF Attribute" entities with 5 different names. This is common implementation for them all:

   SignedAttributes      ::= SET SIZE (1..MAX) OF Attribute
   UnsignedAttributes    ::= SET SIZE (1..MAX) OF Attribute
   UnprotectedAttributes ::= SET SIZE (1..MAX) OF Attribute
   AuthAttributes        ::= SET SIZE (1..MAX) OF Attribute
   UnauthAttributes      ::= SET SIZE (1..MAX) OF Attribute

 Attributes ::=
   SET SIZE(1..MAX) OF Attribute

Method Detail

getInstance

public static Attributes getInstance(Object obj)

Return an Attribute set object from the given object.

Accepted inputs:

• null → null
• Attributes object
• ASN1Set input formats with Attributes structure inside

Parameters:

obj - the object we want converted.

Throws:

IllegalArgumentException - if the object cannot be converted.

getInstance

public static Attributes getInstance(ASN1TaggedObject obj,
                                     boolean explicit)

getAttributes

public Attribute[] getAttributes()

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Produce an object suitable for an ASN1OutputStream.

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object

Returns:

a primitive representation of this object.
