Constructor Details

FDFParser

public FDFParser(RandomAccessRead source)
          throws IOException

Constructs parser for given file using memory buffer.

Parameters:

source - the source of the pdf to be parsed

Throws:

IOException - If something went wrong.

Method Details

initialParse

private void initialParse()
                   throws IOException

The initial parse will first parse only the trailer, the xrefstart and all xref tables to have a pointer (offset) to all the pdf's objects. It can handle linearized pdfs, which will have an xref at the end pointing to an xref at the beginning of the file. Last the root object is parsed.

Throws:

IOException - If something went wrong.

parse

public FDFDocument parse()
                  throws IOException

This will parse the stream and populate the FDFDocument object.

Returns:

the parsed FDFDocument

Throws:

IOException - If there is an error reading from the stream or corrupt data is found.
