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.
