Constructor Detail

### DERInteger

    public DERInteger(int value)

### DERInteger

    public DERInteger(java.math.BigInteger value)

### DERInteger

    public DERInteger(byte[] bytes)

Method Detail

### getInstance

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

  return an integer from the passed in object

  Throws:
    `java.lang.IllegalArgumentException` - if the object cannot be converted.

### getInstance

    public static DERInteger getInstance(ASN1TaggedObject obj,
                                         boolean explicit)

  return an Integer from a tagged object.

  Parameters:
    `obj` - the tagged object holding the object we want
    `explicit` - true if the object is meant to be explicitly tagged false otherwise.
  Throws:
    `java.lang.IllegalArgumentException` - if the tagged object cannot be converted.

### getValue

    public java.math.BigInteger getValue()

### getPositiveValue

    public java.math.BigInteger getPositiveValue()

  in some cases positive values get crammed into a space, that's not quite big enough...

### hashCode

    public int hashCode()

  Specified by:
    `hashCode` in class `ASN1Object`

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`
