Constructor Detail

ASHexString

public ASHexString(byte[] bytes)

Constructor.

ASHexString

public ASHexString(int[] numbers,
                   int bytesToUse,
                   int bytesToPad)
            throws PDFInvalidParameterException

Construct an ASHexString from an array of integers.

Parameters:

numbers - numbers to use in constructing the ASHexString

bytesToUse - number of bytes to use from each number starting with the LSB. Must be from 1 to 4.

bytesToPad - number of bytes to pad in front of each number beyond the number of bytes taken from each number

Throws:

PDFInvalidParameterException - if the bytesToUse is not between 1 and 4

ASHexString

public ASHexString(int[] numbers,
                   int startIndex,
                   int endIndex,
                   int bytesToUse,
                   int bytesToPad)
            throws PDFInvalidParameterException

Throws:

PDFInvalidParameterException

Method Detail

getHex

public byte[] getHex()

Returns hex value of string as byte array.

write

public void write(OutputStream outputStream)
           throws PDFIOException

Writes the ASHexString in to the given OutputStream in the format expected by the PDF Spec.

Parameters:

outputStream - OutputStream to write to.

Throws:

PDFIOException

ASString

write

public void write(OutputByteStream outputStream)
           throws PDFIOException

Writes the ASHexString in to the given OutputByteStream in the format expected by the PDF Spec.

Overrides:

write in class ASString

Parameters:

outputStream - OutputStream to write to.

Throws:

PDFIOException

asString

public String asString()

Description copied from class: ASString

Try to get a chars associated with a byte in this ASString. Note that, because ASString has no encoding, this just uses a series of heuristics to get the chars. No guarantees are made regarding the returned value other than "we tried our best". It may change over time.

Overrides:

asString in class ASString

toString

public String toString()

Description copied from class: ASString

Attempts to get a unicode representation for this unencoded string. No guarantees are made about what is returned.

Overrides:

toString in class ASString
