Method Details

nextParsedToken

public COSBase nextParsedToken()
                        throws IOException

Specified by:

nextParsedToken in class BaseCOSParser

Returns:

The next parsed basic type object from the stream or null if the next token is not a COSBase. Basic types are defined in Chap 7.3 of PDF 32000-1:2008 except for Chap 7.3.10. This method doesn't parse indirect objects definition because they are not permitted in contest stream.

Throws:

IOException - If there is an error during parsing.
