I'm trying to use MailMerge to generate multiple PDFs from documents stored in database. I've tried to avoid storing documents back to file system but it looks I cann't wrap BLOBs a way they can be used directly. I disallowed to use XModel loaded XComponentLoader::loadComponentFromURL from XInputStream and there no way to send InputStream argument for LoadFromURL_impl function in unomailmerge.cxx. Is it possible to expand API to allow use loaded document?
Mail merge is implemented using an implementation of XJob interface [1] (SwXMailMerge). Its "execute" method takes a sequence of NamedValues, which is how you pass parameters there. Extending SwXMailMerge::execute (and SwXMailMerge::setPropertyValue) in sw/source/uibase/uno/unomailmerge.cxx to accept another name-value pair is required for this request. It should basically do a processing of that new pair alternative to what is currently done for UNO_NAME_DOCUMENT_URL.

Can you please guide me a little bit? Thanks!

That is not needed. In addition to trying to change a virtual method (which is a public API), which is impossible, the main thing is that it is not needed. The old "Arguments" is already itself an arbitrary-length sequence of name-value pairs, so all you need to do is to add one more pair into the sequence when you prepare it for calling SwXMailMerge::execute, and then implement the processing of that pair in the function.

So I need to add the pair in SwXMailMerge::setPropertyValue function before executing it. I think that something needs to be done in the elif block in line #934: else if (pData == &m_aDocumentURL) { OUString aText; bOK = rValue >>= aText; if (!aText.isEmpty() && !LoadFromURL_impl( m_xModel, m_xDocSh, aText, true )) throw RuntimeException("Failed to create document from URL: " + aText, static_cast < cppu::OWeakObject * > ( this ) ); m_aDocumentURL = aText; } But I can't figure out what to do here. Can you help?
