public void flush()
PdfObject
behind this wrapper, you have to ensure that this object is added to the document, i.e. it has an indirect reference. Basically this means that before flushing you need to explicitly call PdfObjectWrapper.makeIndirect(PdfDocument)
. For example: wrapperInstance.makeIndirect(document).flush(); Note that not every wrapper require this, only those that have such warning in documentation.
