I'm not familiar with much code beyond the parser and outline (aka bookmarks), but I can say that the parser has a plethora of examples of edge cases. This is due to the very large number of documents which do not conform to the PDF specification. So, in terms of real-world experience of how the theory (PDF spec) doesn't match the real world (non-conforming PDFs), it's an excellent example.
As for the class structure, inheritance, code re-use and so forth, I have only had time to deal with the specific things which I need to fix/enhance/extend, so I don't have a feel for the bigger picture. However, I haven't come across anything which I thought was poorly designed, so I'm inclined to say that it is well done. Another thing to pay attention to are the patches, especially the bugfixes. It shows how one person solved the problem, and then a better way to do it. So you not only learn the best way to do it, but why. For a quick example of this, check out Martijn's patch for PDFBOX-908: https://issues.apache.org/jira/browse/PDFBOX-908 ---- Thanks, Adam From: Kevin Brown <[email protected]> To: [email protected] Date: 04/12/2011 10:28 Subject: Off Topic: pdfbox a good example of a project from which to learn? For those who have worked on or examined the code for this project -- do you think that it is a well put together project, which might be good for a Java programmer to study to improve coding and design ability? - FHA 203b; 203k; HECM; VA; USDA; Conventional - Warehouse Lines; FHA-Authorized Originators - Lending and Servicing in over 45 States www.swmc.com - www.simplehecmcalculator.com Visit www.swmc.com/resources for helpful links on Training, Webinars, Lender Alerts and Submitting Conditions This email and any content within or attached hereto from Sun West Mortgage Company, Inc. is confidential and/or legally privileged.
