  • Field Details

    • data

      protected final byte[] data

    • padBits

      protected final int padBits

  • Constructor Details

    • ASN1BitString

      protected ASN1BitString(byte data, int padBits)

    • ASN1BitString

      public ASN1BitString(byte[] data, int padBits)
      Base constructor.
      Parameters:
      data - the octets making up the bit string.
      padBits - the number of extra bits at the end of the string.

  • Method Details

    • getPadBits

      protected static int getPadBits(int bitString)
      Parameters:
      bitString - an int containing the BIT STRING
      Returns:
      the correct number of pad bits for a bit string defined in a 32 bit constant

    • getBytes

      protected static byte[] getBytes(int bitString)
      Parameters:
      bitString - an int containing the BIT STRING
      Returns:
      the correct number of bytes for a bit string defined in a 32 bit constant

    • getString

      public String getString()
      Return a String representation of this BIT STRING
      Specified by:
      getString in interface ASN1String
      Returns:
      a String representation.

    • intValue

      public int intValue()
      Returns:
      the value of the bit string as an int (truncating if necessary)

    • getOctets

      public byte[] getOctets()
      Return the octets contained in this BIT STRING, checking that this BIT STRING really does represent an octet aligned string. Only use this method when the standard you are following dictates that the BIT STRING will be octet aligned.
      Returns:
      a copy of the octet aligned data.

    • getBytes

      public byte[] getBytes()

    • getPadBits

      public int getPadBits()

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • hashCode

      public int hashCode()
      Specified by:
      hashCode in class ASN1Primitive

    • getLoadedObject

      public ASN1Primitive getLoadedObject()
