  - ### Method Detail

    - #### get

          public Attribute get​(ASN1ObjectIdentifier oid)

      Return the first attribute matching the OBJECT IDENTIFIER oid.
      Parameters:
        `oid` - type of attribute required.
      Returns:
        first attribute found of type oid.

    - #### getAll

          public ASN1EncodableVector getAll​(ASN1ObjectIdentifier oid)

      Return all the attributes matching the OBJECT IDENTIFIER oid. The vector will be empty if there are no attributes of the required type present.
      Parameters:
        `oid` - type of attribute required.
      Returns:
        a vector of all the attributes found of type oid.

    - #### size

    - #### add

          public AttributeTable add​(ASN1ObjectIdentifier attrType,
                                    ASN1Encodable attrValue)

      Return a new table with the passed in attribute added.
      Parameters:
        `attrType` - the type of the attribute to add.
        `attrValue` - the value corresponding to the attribute (will be wrapped in a SET).
      Returns:
        a new table with the extra attribute in it.

    - #### remove

          public AttributeTable remove​(ASN1ObjectIdentifier attrType)
