- - ### Constructor Detail

    - #### ASN1Enumerated

          public ASN1Enumerated(int value)

      Constructor from int.
      Parameters:
        `value` - the value of this enumerated.

    - #### ASN1Enumerated

          public ASN1Enumerated(java.math.BigInteger value)

      Constructor from BigInteger
      Parameters:
        `value` - the value of this enumerated.

    - #### ASN1Enumerated

          public ASN1Enumerated(byte[] contents)

      Constructor from encoded BigInteger.
      Parameters:
        `contents` - the value of this enumerated as an encoded BigInteger (signed).

  - ### Method Detail

    - #### getInstance

          public static ASN1Enumerated getInstance(java.lang.Object obj)

      return an enumerated from the passed in object
      Parameters:
        `obj` - an ASN1Enumerated or an object that can be converted into one.
      Returns:
        an ASN1Enumerated instance, or null.
      Throws:
        `java.lang.IllegalArgumentException` - if the object cannot be converted.

    - #### getInstance

          public static ASN1Enumerated getInstance(ASN1TaggedObject taggedObject,
                                                   boolean declaredExplicit)

      return an Enumerated from a tagged object.
      Parameters:
        `taggedObject` - the tagged object holding the object we want
        `declaredExplicit` - true if the object is meant to be explicitly tagged false otherwise.
      Returns:
        an ASN1Enumerated instance, or null.
      Throws:
        `java.lang.IllegalArgumentException` - if the tagged object cannot be converted.

    - #### getTagged

          public static ASN1Enumerated getTagged(ASN1TaggedObject taggedObject,
                                                 boolean declaredExplicit)

    - #### hasValue

          public boolean hasValue(int x)

    - #### hasValue

          public boolean hasValue(java.math.BigInteger x)

    - #### intValueExact

          public int intValueExact()

    - #### hashCode

          public int hashCode()

      Specified by:
