  • Constructor Details

    • ByteRange

      public ByteRange(int[] byteRangeArray)
      This constructor represents a ByteRange extracted from a Signature Dictionary of a signed/timestamped revision
      Parameters:
      byteRangeArray - byte range of a signature/timestamp

  • Method Details

    • getLength

      public int getLength()
      Returns a total revision length
      Returns:
      length

    • getFirstPartStart

      public int getFirstPartStart()
      Returns the first byte number of the first part of the revision
      Returns:
      first byte

    • getFirstPartEnd

      public int getFirstPartEnd()
      Returns the last byte number of the first part of the revision
      Returns:
      first part end byte

    • getSecondPartStart

      public int getSecondPartStart()
      Returns the first byte number of the second part of the revision
      Returns:
      second part start byte

    • getSecondPartEnd

      public int getSecondPartEnd()
      Returns the last byte number of the second part of the revision
      Returns:
      second part end byte

    • toBigIntegerList

      public List<BigInteger> toBigIntegerList()
      Transforms the ByteRange to a list of BigIntegers
      Returns:
      a list of BigIntegers

    • isValid

      public boolean isValid()
      Returns if the /ByteRange is valid
      Returns:
      TRUE if the /ByteRange is valid, FALSE otherwise

    • setValid

      public void setValid(boolean valid)
      Sets whether /ByteRange has passed the verification against the PDF document
      Parameters:
      valid - if the /ByteRange is valid

    • validate

      public void validate()
      Checks a validity of the ByteRange according to PDF specifications. This method verifies the array of integers representing the ByteRange itself without taking into account the PDF document, nor the /Contents octets. NOTE : this method throws a IllegalInputException if an error is encountered and does not update the state of the object. Please use setValid(valid) method to define the validity of the ByteRange.
