[xwiki-devs] [PROPOSAL] Add XWikiAttachmentContent#setContent() which returns an OutputStream to write content to.

Hi, In the development of Cassandra attachments, I found I want to load an attachment one chunk at a time and write that chunk to a provided OutputStream, this is how I envision next generation Hibernate attachments working too. I would like to add to XWikiAttachmentContent: public OutputStream addContent(); which returns an OutputStream that allows writing the attachment content and upon close, sets the attachment content as dirty and resets the size field. WDYT? Caleb
