Package org.bouncycastle.asn1.cms

## 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​(java.lang.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:
        `java.lang.IllegalArgumentException` - if the object cannot be converted.

          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.
