Field Detail

• PDFDOCENCODING

  public static char[] PDFDOCENCODING

  Mapping between PDFDocEncoding and Unicode code points.

Constructor Detail

• Literal

  public Literal()

  Creates an instance of a string literal

Method Detail

• appendHex

  public void appendHex(int ch)
                 throws PdfException

  Append a hex character. This is used only for hex literals (those that start with '<').

  Parameters:

  ch - The integer 8-bit code for a hex character

  Throws:

  PdfException

• processLiteral

  public long processLiteral(Tokenizer tok)
                      throws IOException

  Process the incoming characters into a string literal. This is used for literals delimited by parentheses, as opposed to hex strings.

  Parameters:

  tok - The tokenizer, passed to give access to its getChar function.

  Returns:

  true if the character was processed normally, false if a terminating parenthesis was reached.

  Throws:

  IOException

• convertHex

  public void convertHex()
                  throws PdfException

  Convert the raw hex data. Two buffers are saved: _rawBytes for the untranslated hex-encoded data, and _value for the PDF or UTF encoded string.

  Throws:

  PdfException

• isPDFDocEncoding

  public boolean isPDFDocEncoding()

  Returns true if this string is in PDFDocEncoding, false if UTF-16.

• setPDFDocEncoding

  public void setPDFDocEncoding(boolean pdfDocEncoding)

  Sets the value of pDFDocEncoding.

• isDate

  public boolean isDate()

  Returns true if the string value is a parsable date. Conforms to the ASN.1 date format: D:YYYYMMDDHHmmSSOHH'mm' where everything before and after YYYY is optional. If we take this literally, the format is frighteningly ambiguous (imagine, for instance, leaving out hours but not minutes and seconds), so the checking is a bit loose.

• parseDate

  public Date parseDate()

  Parse the string value to a date. PDF dates conform to the ASN.1 date format. This consists of D:YYYYMMDDHHmmSSOHH'mm' where everything before and after YYYY is optional. Adobe doesn't actually say so, but I'm assuming that if a field is included, everything to its left must be included, e.g., you can't have seconds but leave out minutes.

• isPDFACompliant

  public boolean isPDFACompliant()

  Returns true if this token doesn't violate any PDF/A rules, false if it does.
