PoDoFo::PdfXRefStream::~PdfXRefStream | ( | ) | [virtual] |
Destruct the XRef table
void PoDoFo::PdfXRefStream::BeginWrite | ( | PdfOutputDevice * | pDevice | ) | [protected, virtual] |
Called at the start of writing the XRef table. This method can be overwritten in subclasses to write a general header for the XRef table.
pDevice | the output device to which the XRef table should be written. |
Reimplemented from PoDoFo::PdfXRef.
void PoDoFo::PdfXRefStream::EndWrite | ( | PdfOutputDevice * | pDevice | ) | [protected, virtual] |
Called at the end of writing the XRef table. Sub classes can overload this method to finish a XRef table.
pDevice | the output device to which the XRef table should be written. |
Reimplemented from PoDoFo::PdfXRef.

unsigned int | nFirst, | |||
unsigned int | nCount | |||
) | [protected, virtual] |
Begin an XRef subsection. All following calls of WriteXRefEntry belong to this XRef subsection.
pDevice | the output device to which the XRef table should be written. | |
nFirst | the object number of the first object in this subsection | |
nCount | the number of entries in this subsection |

Write a single entry to the XRef table
pDevice | the output device to which the XRef table should be written. | |
lOffset | the offset of the object | |
lGeneration | the generation number | |
cMode | the mode 'n' for object and 'f' for free objects | |
lObjectNumber | the object number of the currently written object if cMode = 'n' otherwise undefined |
