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

Throws:

IOException - If there is an error during parsing.

nextNumberOrIndirectReference

public COSBase nextNumberOrIndirectReference()
                                      throws IOException

Returns:

The next parsed numeric object from the stream or the next indirect object in case the number is an object number . Numeric objects are defined in Chap 7.3.3 of PDF 32000-1:2008. Indirect objects are defined in Chap 7.3.10 of PDF 32000-1:2008

Throws:

IOException - If there is an error during parsing.
